U.S. roads, bridges are decaying despite stimulus influx

Gary Stoller, USA TODAY
NEW FAIRFIELD, CONN. - As car after car is jolted by cracked asphalt on a less-than-1-mile stretch of road connecting Route 39 to the New York border, it becomes clear why state transportation officials grade the pavement of this winding western Connecticut road as being in poor condition.
Edges of the two-lane road - where a sign says Col. Henry Ludington passed by in 1777 to repel "British raiders" - are worn and recessed, allowing rainwater to pool.
Connecticut has the nation's second-highest percentage of major roads - 48%, or 1,268 miles - with pavement in "poor" condition, and 25 other states have 20% or more in such condition, according to an exclusive analysis of the Federal Highway Administration's (FHWA) most recent data by transportation research group TRIP and USA TODAY.
Indeed, just 38% of the pavement on roads stretching miles across the USA is in "good" condition, according to the analysis, while about one in 10 of the nation's bridges are "structurally deficient."
Roads with pavement in poor condition have "advanced deterioration" and typically require structural repair or replacement, according to the FHWA. Such roads, TRIP says, may have ruts, cracks and potholes that give millions of Americans rough rides that increase repair costs and fuel consumption.
The analysis concludes that the nation's roadways - critical for moving people, goods and services - are in disrepair, and even states with mostly "good" roads have stretches of pavement, as well as bridges, that are in dire need of upgrades.
State, federal and local funding levels for road and bridge improvements are not adequate to meet the nation's growing needs. About $85 billion is required annually to improve the condition of roads and bridges - nearly double what was spent in 2008, according to the Department of Transportation's 2010 report to Congress.
And drivers across the USA are paying the price.

The 6 Craziest Roads In The World

The 6 Craziest Roads In The World


Guoliang Tunnel, China


Only 16 feet tall and 13 feet wide, this 3/4-mile tunnel was built by villagers in 1972, desperate to connect their village to the world outside the Taihang Mountains. Many of the Guoliangers died during its five-year construction



Passo dello Stelvio, Italy

Passo dello Stelvio, ItalyWhile Stelvio Pass is only the second highest paved mountain pass in the Alps at 9045 feet, its passages are much more precarious.

Dades Gorge Road, Morocco

Dades Gorge Road, MoroccoLocated way up in the High Atlas Mountains at the edge of the Sahara Desert, the cleft features cliffs towering up to 1600 feet tall, with some of the roads going through fissures only 30 feet wide

Yungas Road (Road of Death), Bolivia

Yungas Road (Road of Death), BoliviaOnce named the “world’s most dangerous road,” El Camino de la Muerte is a 38-mile long journey through the mountains, leading from La Paz to Coroico. It is estimated that 200-300 travelers yearly die while traversing it.

Atlanterhavsveien (Atlantic Ocean Road), Norway

Atlanterhavsveien (Atlantic Ocean Road), NorwayDespite looking menacing in bad weather conditions, Atlanterhavsveien is actually ranked as one of the best scenic roads in the world, with insane curves and epic vistas.

Halsema Highway, Philippines

The highest highway in all of the Philippines, the Halsema Highway takes about six hours to traverse. Despite its zigzag design, it has a relatively low number of deaths given its extreme altitudes, and looks fantastic.

Massachusetts Governor Deval L. Patrick and his administration are moving forward with a $250 million plan that would replace toll collectors in the state with all-electronic tolling, according to a report from The Republican.
In addition to the push for all-electronic tolling, officials are working on a plan that would reinstate passenger-vehicle tolls between Exits 1 and 6, beginning October 15. State legislators approved a law in July that allows the change to happen.
The Massachusetts Department of Transportation (MassDOT) announced the all-electronic tolling plan at a hearing Thursday night in Boston.
The system would detect E-ZPass transponders and take pictures of license plates of vehicles without transponders. Drivers without transponders would receive a pay-by-plate fee to cover the cost of image processing and billing.
Cynthia Roy Gonzalez, director of communications for MassDOT, said the all-electronic systems will save the agency $50 million a year by eventually terminating about 400 toll collector positions. The system would cost approximately $250 million over 10 years to construct, operate and maintain.
MassDOT plans begin all-electronic tolling next year with southbound traffic at the Tobin Bridge in Boston, with the entire system operating electronically by 2017.

What is Asphalt?

What is Asphalt?
"What is asphalt?" you ask. Asphalt is the sustainable material for building pavements. It's smooth, so vehicles consume less fuel and produce lower emissions; it's quiet, so expensive noise walls don't need to be constructed; it's safe, providing excellent gripping power; and it's durable, so that the road never needs to be removed and replaced. It is also the most recycled material in the U.S.
Oh -- your question really was "What is asphalt made of?" Well, then! Asphalt is made from stones, sand, and gravel, held together by asphalt cement. View the video below to see what happens at an asphalt plant.

Construction Materials Prices Flat in July Despite 4% Crude Inflation

Construction Materials Prices Flat in July Despite 4% Crude Inflation

Source: ASSOCIATED BUILDERS AND CONTRACTORS INC. 
Created: 

Construction materials prices remained stable from June to July but are up 2 percent compared to July 2012, according to the latest Producer Price Index release by the U.S. Labor Department. Nonresidential construction materials prices were down 0.1 percent for the month and are 1.8 percent higher than one year ago.
Crude energy prices climbed 4 percent in July and crude petroleum prices jumped 10.6 percent. Year over year, crude energy prices are up 21.6 percent.
Prices for plumbing fixtures and fittings increased 2.1 percent from June and are up 3.1 percent annually.
Prices for prepared asphalt, tar roofing and siding rose 2 percent for the month and are 4.7 percent higher than the same time last year.
Iron and steel prices increased 1.7 percent in July, but remain 2.8 percent lower on an annual basis.
Prices for steel mill products edged 0.4 percent higher in July, but remain 6.1 percent lower than one year ago.
Prices for concrete products were 0.5 percent higher for the month and are up 3.3 percent compared to last year.
Key construction inputs that did not experience price increases for the month include fabricated structural metal products, which were unchanged and have been flat on a year-over-year basis.
Softwood lumber prices slipped for the third straight month, down 0.5 percent in July, but are still 9.9 percent higher than one year ago.
Nonferrous wire and cable prices fell 1.1 percent for the month and are down 3.9 percent from July 2012.
Overall, the nation’s wholesale goods prices were flat in July and are 2.1 percent higher than the same time last year.
"According to today’s Producer Price Index report, nonresidential construction materials remained well behaved, with aggregate price levels falling 0.1 percent in July and inputs to nonresidential construction increasing less than 2 percent during the past year" said ABC Chief Economist Anirban Basu. "Input price inflation is rarely so well contained.
"However, looking beyond the headline number reveals a different story. In July, many nonresidential materials prices expanded, some of them significantly. For instance, the largest monthly increase occurred in crude energy, with prices rising 4 percent. Other categories registering monthly increases in excess of 1 percent were plumbing fixtures and fittings, prepared asphalt, tar roofing and siding, and iron and steel. For contractors, the implication is that not all materials prices are well behaved.
“Prices fell in certain categories, including softwood lumber and nonferrous wire and cable. Those declines help explain the flat overall PPI number for the month, but do not change the fact that materials prices remain more volatile than they might appear at first glance.”

When Post road will be fix?

NORTH KINGSTOWN — Work on the first phase of the Post Road sewer project is wrapping up, and the temporary repaving of the rugged roadway could begin as early as late August.
The second phase of the project is still in limbo as town officials continue to look for a site to build a pumping station.
Public Works Director Phil Bergeron said the work on Post Road that has drivers stuck in traffic daily is part of a National Grid project to replace a gas main. “All our work under the road is done,” he said Tuesday.
A request to begin repaving the roadway with a temporary overlay is currently being reviewed by the state Department of Transportation. A final repaving of the roadway won’t occur until the second phase of the project is complete; that won’t happen until a location is found for a pumping station.
In January, the Rhode Island State Police denied a request to locate a pumping station on the property of its Wickford Barracks, located at 7875 Post Road.
“Because the Rhode Island State Police is considering selling this property and moving the Wickford Barracks to a new location within the next few years, Col. [Steven] O’Donnell will not allow the easement,” State Police Major Karen D. Pinch wrote in a letter to North Kingstown Police Chief Thomas Mulligan on Jan. 11.
That has delayed the second phase of the project, as officials look for a new pump site.
“We could have been doing work right now,” Bergeron noted.
There are currently two alternative sites that the town is looking at: Smith’s Castle property, at 55 Richard Smith Drive just off Post Road; and a three-quarter-acre parcel owned by the state near the intersection of Stony Lane and Huling Road.
The town would have to purchase the small property from the state; the assessed value is about $80,000, according to Bergeron. If those options don’t pan out, Bergeron said the town would ask the state police to reconsider its decision.
“I guess if everything else falls through, then we have to go back to them,” he said.
In November 2009, voters approved a $10 million bond to fund the installation of sewers along Post Road, with the first phase covering the southern stretch of Post Road from the Route 403 overpass to just south of the West Bay YMCA. The work includes extending sewer service to several residential properties on Camp Avenue.
The first phase consists of a pumping station on Camp Avenue at Tully Way; 4,200 feet of gravity sewer line on Post Road and Camp Avenue; and 3,500 feet of pressurized piping on Camp Avenue. It also includes 1,400 feet of water main improvements on Post Road.
In total, that portion of the project will service 205 commercial acres and 30 residential properties.
In November 2010, voters approved another $9.2 million bond to finance the design and installation of sewers from Dana Drive to the Wickford Barracks, including the Shore Acres neighborhood. This portion of the project will service 105 acres of commercial land and 149 residential properties.
Bergeron said he doesn’t expect the second phase to be started until after the winter.
The Town Council will meet Aug. 5 to discuss the possibility of going to bond for a third phase of the project, and will talk about what portions of town a third phase could cover.
“Do we go north of Route 403? Do we go into Wickford? Ultimately, it’s a council decision,” Bergeron said.
The council also will discuss how to assess the sewer fees to property owners once the sewer system is up and running. “We want to be as fair and equitable to property owners as possible,” Bergeron said.
He added it is important for property owners to be aware of the upcoming discussions and participate in future public hearings.
“They need to know what’s going on,” Bergeron said. “We don’t want them to get an assessment bill and say, ‘We didn’t know anything about this.’”
The Town Council will meet Aug. 5 at 7 p.m. at Beechwood: A Center for Life Enrichment, 44 Beach S

Types of Asphalt Pavement

Types of Asphalt Pavement


In addition to being smooth, durable, safe, and quiet, asphalt is the most versatile pavement material. Pavement structures can be designed to handle any load, from passenger cars to heavy trucks. Surface mixes can be customized to absorb noise, to reduce splash and spray during rainstorms, and even to help treat rain water. 

Busy commercial airports such as Baltimore-Washington International, Oakland International, San Francisco International, McCarren (Las Vegas), Pearson International (Toronto), and Logan International (Boston) have main runways surfaced with HMA. Asphalt is also used extensively on runways at general aviation airports. Asphalt's speed of construction makes it an ideal choice for rehabilitation of busy aviation facilities.

At racetracks, asphalt pavements provide smooth driving surfaces combined with the excellent traction demanded by professional stock car racing. Of the 33 NASCAR race tracks across the country, 31 have asphalt surfaces. Of the 88 race tracks listed for the NASCAR Short Track series, 66 are asphalt, 21 are dirt or clay, and 1 is concrete.

Whether on the road, in a parking lot, or at an airport, asphalt pavements add up to the best value for the taxpayer dollar, with the lowest life cycle cost and the highest residual value.

Can Asphalt affect the environmental?

Sunset_Hot-Air_Balloon_Asphalt_RoadAsphalt is the sustainable material for constructing pavements. From the production of the paving material, to the placement of the pavement on the road, to rehabilitation, through recycling, asphalt pavements minimize impact on the environment. Low consumption of energy for production and construction, low emission of greenhouse gases, and conservation of natural resources help to make asphalt the environmental pavement of choice. 

I. Energy and Recycling

Less energy consumed in building pavements
Asphalt pavements require about 20 percent less energy to produce and construct than other pavements.1

Less energy consumed by the traveling public 
Congestion leads to unnecessary consumption of fuel and production of emissions. Reducing congestion by constructing asphalt pavements just makes sense. Asphalt pavements are faster to construct and rehabilitate. And, a new or newly rehabilitated asphalt pavement can be opened to traffic as soon as it has been compacted and cooled. There is no question of waiting for days or weeks for the material to cure.

America’s leading recycler
The asphalt industry reclaims about 65 million tons of its own product every year, and reuses or recycles about 99 percent of it. This makes it America’s number one recycler.

Other materials are routinely recycled into asphalt pavements. Some of the most common are rubber from used tires, glass, blast furnace slag, and asphalt roofing shingles

When I started in the asphalt Industry





“I started in the asphalt industry in 1986 with experience in quality control,asphalt mix design, management, production and project supervisor.There is nothing more rewarding than helping people have their driveway either brushed up with a little bit of maintenance or have a brand new driveway installed. The driveway is the first thing people see as they drive up to our home and a beautiful well groomed driveway gives a great first impression! When I first got into the business, it amazed me at how many people loved having a nice driveway! While there are a percentage of people out there who just want a basic hard surface to drive and park on, some homeowners want their driveway to look beautiful all the time! Those are the people I love working with. It’s a very fun and fulfilling business! But unfortunately the industry is full of dishonest and unethical contractors who are out there with one goal in mind… to make high profits at the expense of quality! They don’t put one thought into building long term repeat business. Instead, they’re only concerned about short term greed. I've seen many examples of people who've lost hundreds of dollars and some even several thousand dollars… in one single job! It’s very frustrating to see people being taken such advantage of. So I started UNO paving to help educate homeowners on the proper installation and maintenance of driveways and avoid being ripped off.”

Cost of Asphalt Rises, Affecting Repaving

THE Clifton Avenue Bridge over Interstate-280 and the New Jersey Transit railroad tracks in Newark is a cratered moonscape, a patchwork of cracks, pockmarks and potholes that make vehicle shock absorbers rattle and drivers bounce like Muppets.
Alan Zale for The New York Times

In the Region

Long Island, Westchester, Connecticut and New Jersey
Go to Complete Coverage »
The bridge is scheduled to be replaced this summer. But because of the skyrocketing cost of asphalt — one more bit of fallout from soaring oil prices — this project, like more than a dozen statewide, may be held off until next year, New Jersey officials said.
That upsets Ruben Morales, who lives nearby and drives his Mercedes-Benz CL500 and his motorcycle over the rough terrain daily.
“I’ve bent the rims of my motorcycle on those potholes,” said Mr. Morales, 29, a corrections officer. “It’s been bad for years.”
As the cost of asphalt, a petroleum-based product, keeps going up, state and local officials around the region are postponing road repairs that are not deemed crucial and all but halting new road construction.
In Westchester and on Long Island, the New York State Department of Transportation is working to make all necessary road repairs because of the high level of traffic in and out of New York City, said Skip Carrier, a department spokesman.
“It’s a question of how quickly we can get to the projects, not that we won’t do the projects,” he said. “It’s a necessary part of maintaining our infrastructure; we have to do the work.”
The highways on Long Island, he said, are not only vital to commuters but also to commercial and freight traffic. In Westchester, he said, the high volume of commuter traffic makes road repairs there crucial.
Mr. Carrier said, however, that Gov. David A. Paterson had asked the Transportation Department to cut its budget by more than 3 percent, which could affect how quickly roads get repaved.
Asphalt is made of two parts — an aggregate, of stones or gravel, and a binder, a sticky tarlike substance made from petroleum. The cost of the binder, which makes up 6 percent of the mixture that covers roads, has gone up 16 percent since April and more than 40 percent since last year, said Kenneth D. Simonson, chief economist for the Associated General Contractors of America, a trade association. The cost of asphalt itself has gone up more than 5 percent since April and 10 percent in the past year, he said.
The price of the diesel fuel needed to help crush stone from quarries and haul asphalt to road construction sites is also cranking up costs, Mr. Simonson said. So are new technologies that refine crude oil into more valuable petroleum products, like diesel and gasoline, and leave less low-grade material for road paving.
The cost of fuel means that drivers are driving less, which means less gasoline tax revenue for states to fill Transportation Department coffers, said David Weinstein, a spokesman for AAA Mid-Atlantic. And high diesel costs coupled with the housing slump have resulted in fewer tractor-trailers hauling home building materials and furniture, resulting in less diesel tax revenue for states, he said.
Between January and May 2004, New Jersey took in more than $198 million in gasoline taxes and more than $46 million in diesel taxes, Mr. Weinstein said. For that period this year, those numbers were around $184 million and $45 million, respectively.
Even though the price of asphalt has doubled since 2005, the Connecticut Department of Transportation is moving ahead with all scheduled repairs, 250 to 300 miles of two-lane roads, said Kevin Nursick, a department spokesman.
“For years to come it would certainly be a factor in determining which projects move ahead,” he said.
Having seen the cost of asphalt rise drastically last summer, Westchester road officials budgeted for what they thought was a high estimate of this year’s increase, 15 percent. But the price went up nearly 20 percent, said Ralph Butler, the county’s commissioner of public works.
Westchester is moving forward with repaving almost 12 miles of road at a cost of almost $9 million, or nearly $90 a ton of asphalt, up from $72 last year, Mr. Butler said.
But Bergen County, N.J., will repave only 23 miles of road, not the 32 that were scheduled, because of the cost of asphalt, said Mabel Aragon, a county spokeswoman.
New Jersey, according to its Transportation Department, paid $49.46 per ton for asphalt in 2001 and will pay $88.71 this year — a 79 percent increase in seven years.
IN addition to $200 million budgeted for road repairs this summer, the New Jersey Transportation Department also budgeted up to $25 million for fuel price adjustments, money a contractor can apply for should the price of fuel jump before the completion of a job. Despite that, many contractors say they are working for less profit, and therefore can hire fewer workers.
Chris Janeira, 24, of Kearny, has worked paving roads for seven years. This year, he has been doing odd jobs to make ends meet because he has less paving work.
“I keep calling, they keep saying, ‘Next month, next month, costs are too high right now,’ ” said Mr. Janeira, who is a member of Heavy and General Construction Laborers Union Local 472. “This is a bad summer.”
New Jersey had set an aggressive goal to repave enough roads so that Transportation Department officials would have to fill only 50,000 to 75,000 potholes annually, Commissioner Kris Kolluri said. Two years ago, the state filled 300,000 potholes; last year, 200,000. Rising asphalt costs will make it more difficult to cut that number more this year, he said.
“On the one hand, we have inflation; on the other we have a financial crisis, so it becomes a very challenging balancing act,” he said. “But it’s about efficiency and safety.”
Though New Jersey officials say they are proceeding with all scheduled road work, there is anecdotal evidence that repairs are needed. According to AAA, there has been a 12.8 percent increase in the number of flat tires reported to the organization on roads throughout New Jersey from May 1 through June 17.
Might delayed repairs result in less roadwork this year and therefore fewer traffic jams? Unfortunately not, Mr. Kolluri said.

“I wish that was the silver lining around this dark issue,” he said. “However, traffic congestion is part of how the network works.”

Texas county tries “mechanical concrete”

Texas county tries “mechanical concrete”


A major Texas county is trying out a road bed system that uses old tires. Thousands of them, not chewed up into small pieces but basically intact. Once the worn out tires come off a vehicle and head to used tire dumps, this system steps in, removes the sidewalls and uses the old treads as a container for crushed rock. Once the sidewalls are removed, the treads are set on the ground and fastened together and then crushed rock is poured over the tires, with the road finish of choice–gravel, concrete or asphalt–installed over them The old tire treads are “geo-cylinders,” says the man behind the process, Sam Bonasso. They hold crushed rock, gravel or sand in place as a “mechanical concrete” in a roadbed. The system is being tried in various places in the country, says Bonasso, and its main advantages are its “green” value (from using all those landfill tires), its strength (high) and its cost (low). - See more at: http://www.betterroads.com

Top 20 U.S. Cities with Most New Construction

Top 20 U.S. Cities with Most New Construction

According to McGraw-Hill Construction data, new construction for the entire country was up 10 percent in 2012 and is projected to climb another 12 percent in 2013.
Using building data for the nation’s Metropolitan Statistical Areas (MSAs), McGraw-Hill determined the 20 places where the most money has been spent so far this year on new construction (from January through May, 2013). The determining factor was the dollar amount of new construction starts, or projects where ground has been broken and work begun, for structures that fall under the “Total Building” umbrella. Total building includes single-family home construction, multifamily home construction, office space, retail space, warehouses, healthcare facilities, educational buildings, manufacturing plants and research facilities. Money spent on public works projects and electric utility construction was not factored in.
Here's the list of the top 20 metros with new construction spending:

BBB warns about asphalt paving scam

BBB warns about asphalt paving scam


The Better Business Bureau is warning consumers about a scam involving door-to-door salesmen offering low-cost quotes on asphalt paving.
Consumers were approached by a Johnny Young, who operates an asphalt paving business known as Asphalt Construction. A BBB investigation unveiled that the company also does business as JRY Construction, Johnny Asphalt, Johnny Young Asphalt and Construction, William Wells Asphalt Construction Co. and Young & Cooper Asphalt.
Senior citizens and a non-profit organization complained that Young came to their residence and place of business offering to pave their driveways with “leftover” asphalt. He was fast-talking and provided no written cost estimate prior to paving. The consumers’ driveways were paved immediately with no notification of their right to cancel within three business days. Consumers complained that the billed amount was substantially more than expected and is anywhere from $3,000 to $8,000. Many were surprised that the price was based on square yards and not cubic yards. Consumers also have complained about the poor workmanship of the paving and non-responsiveness by Young after the initial business transaction.
Young has been identified as approximately 5 feet, 10 inches tall, husky, dark-haired, middle-aged and driving a white truck. He has been operating in the greater Akron and Canton areas. His business address has been tied to rental mailboxes in Kent and Stow. His home address appears to be transitorily in Sunset, La.

To avoid becoming a victim, the BBB says to beware of:

1. A company that knocks on your door claiming to have “leftover” asphalt or other materials. Leftover hot-mix asphalt would be too cold to place properly, while cold mix is used exclusively for small patches, not general paving. Asphalt is a perishable product and, if it cools too much, it is useless as a hot mix paving product.
2. Deals that seem “too good to be true.” If the quoted price seems very low, chances are the quality of the work will be low as well.
3. Cash-only terms. Most reputable contractors take checks and don’t require cash-only terms.
4. “One-time offer” price quotes. Reputable contractors will provide a quote before doing any work so that the homeowner has a chance to shop around.
5. Door-to-door sales. Reputable asphalt contractors do not sell their products door-to-door. Consumers should be very suspicious of anyone appearing at their front doors offering low-cost asphalt.
6. Vehicles with out-of-state license plates. This type of scam many times will be run by persons traveling from other states.

Florida man designs hurricane-resistant traffic signal hangers




By: Amanda Bayhi


The Florida Department of Transportation (FDOT) is installing pivotal hangers at traffic signals throughout the state to protect the signals from hurricane damage, according to a report from the Sun Sentinel. The hangers, designed by Florida native Robert Townsend, will be retrofitted onto existing traffic signals in Palm Beach and Broward Counties. FDOT will spend a total of $2.6 million adding the hangers to a combined 106 intersections in those counties. The hangers will also be standard in Florida on new traffic signals that do not require steel mast arms. Townsend, a Palm Beach County home designer and master woodworker, said he began working on the design after experiencing traffic chaos brought on by many hurricanes in 2004 and 2005. When he discovered the county’s standard procedure of removing traffic signals as a storm precaution–due to the massive number of signals lost in previous storms–he decided to work on a solution. 

“The whole goal is to have a controllable intersection after a storm,” Townsend said. Townsend’s pivotal design came about after he realized the main problem originated with the aluminum and wire hangers and the black box connected to them. His solution was to create pivoting hangers for flexibility in high winds, and to reinforce the black box. “It allows the signal to rotate, but it doesn’t allow bouncing,” Townsend said. “Bouncing is what destroys traffic signals.” The new design allows traffic signals to withstand up to 110-mph winds. - See more at: http://www.betterroads.com/fla-man-designs-hurricane-resistant-traffic-signal-hangers/?utm_source=daily&utm_medium=email&utm_content=07-18-2013&utm_campaign=BR&ust_id=6d66fcfd7c&*#sthash.qaWmQFeP.dpuf

Alaska’s “road to nowhere”


Alsaka's "road to nowhere" would have led to the proposed Gravina Island Bridge, now known as "the bridge to nowhere." (Photo: Tom Brady / Flickr)


Maybe someone is getting ready to take the “dead end” sign off America’s most infamous non-bridge. According to the Associated Press, Alaska has “proposed six ‘build’ alternatives to improve access between the Southeast Alaska community of Ketchikan and Gravina Island, where the Ketchikan International Airport is located. The alternatives include two bridge and four ferry options; there also is a no-action alternative. Comments are being taken through Aug. 13, with a goal of reaching a decision by next spring.” This is of course the non-bridge that caused vice presidential candidate Sarah Palin to say she’d told Congress “thanks but no thanks” for the bridge funding even though she asked for, received and kept the funding.

“Pothole Robin Hood” aims to fix 100 potholes in Jackson, Miss.






The man, who goes by the name “Chane,” said he takes asphalt from the city, repairs potholes and writes “citizen fixed” on the filled holes. “It’s sort of like Robin Hood. Once we saw that people were appreciating what we did, we went out again and made a goal of fixing 100 potholes,” Chane said. Chane, with the help of his girlfriend, has filled 55 potholes. Chane said he began work on the city’s potholes because Jackson has “a big infrastructure problem” and the “city simply does not have the budget.” In fact, Jackson resident Zachary Boozer pointed out that the potholes “are pretty widespread in all areas of the city,” creating cracks in the already-crumbling streets. “People joke that Jackson is a Six Flags because the roads are so bumpy,” Boozer said, adding that sinkholes have also become a major problem in the city. “People have been falling in them. A car fell in one too.” The Jackson Police Department is investigating Chane’s actions and how he got the asphalt. Police have not decided whether to press charges. Chane says he is only trying to help the city, not commit a crime. “We’re not trying to be thieves, or steal from the city,” Chane said. “We’re just trying to put the asphalt to use.” -

Benefits of Sealcoating Asphalt


There are many benefits to sealcoating the asphalt to your driveway or parking lot. Think of sealcoating more of as a preventative maintenance for your diveway or parking lot, similar to how you paint your home to keep the weather from deteriorating the wood.
Sealcoating the asphalt, seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material. The dark black color of newly applied sealcoat improves the appearance of new and old asphalt, making your driveway or parking lot look near brand new.
New sealcoating can preserve the resilience of asphalt surfaces and help hide small cracks, patches and rough spots as well as making traffic lines on parking lots more visible. Sealcoat that is applied correctly makes your asphalt driveway look cleaner because rain washes dirt and debris easily away from the smooth, non-porous surface.

Construction Unemployment Falls to 9.8 Percent

Unemploymet Rate Lowest June Level Since 2008
Unemployment Rate Lowest June Level Since 2008
The unemployment rate for construction workers fell below double digits in June for the first time since 2008 as every segment of the industry added employees, according to an analysis of new government data by AGC of America. Association officials said the relatively positive jobs report for the sector highlights the need to address potential shortages of skilled and entry-level workers.
“Construction employment in June was the highest since August 2009,” said Ken Simonson, the association’s chief economist. “But employment is still down by one-quarter from the peak more than seven years ago. Many of those laid-off workers have left the industry—whether for employment elsewhere, more education or retirement—and construction companies face a looming worker shortage.”

Spring Renews 2013 Construction Industry Forecast


Spring Renews 2013 Construction Industry Forecast


Construction-industry economists brought together for a Reed Construction Data webcast in May revisited 2013 forecasts through the lens of first-quarter results.
The various sectors of the construction economy presented a mixed bag of performance in the first quarter of 2013, but the consensus among Bernard Markstein, chief economist with RCD; Kermit Baker, chief economist with the American Institute of Architects; and Ken Simonson, chief economist with the Associated General Contractors, is that the industry continues to grow at about the same pace as in 2012.It’s agonizingly slow but consistent with earlier forecasts, and far better than the slide the industry experienced from 2008 to 2011. A little attention to the various sectors quickly identifies the best business opportunities.

Housing starts were up 28% in 2012, and the average of nine forecasters suggests +30% to just over 1M starts in 2013. Simonson expects multifamily construction starts to continue growing through 2014, but says the single-family rise could flatten by year's end as buyers in select markets succumb to rising prices and tight lending

The use of Fiber in Asphalt



A mixture of polypropylene and aramid fibers was used in this study to evaluate the
performance characteristics of a modified asphalt mixture. In coordination with the City of
Tempe, an asphalt concrete conventional mixture was selected for paving on Evergreen Drive in
Tempe, Arizona. The designated road section within the construction project utilized two asphalt
mixtures as part of this study: a control mix with no fibers, and a mixture that contained one
pound of fibers per ton of asphalt concrete. The laboratory experimental program included:
triaxial shear strength, dynamic (complex) modulus, repeated load permanent deformation, beam
fatigue, crack propagation, and indirect diametral tensile tests. The data was used to compare the
performance of the fiber modified mixture to the control. The results showed that the fibers
improved the mixture’s performance in several unique ways against the anticipated major
pavement distresses: permanent deformation, fatigue cracking, and thermal cracking.

In this study, a construction project to utilize fibers in conventional asphalt concrete
mixture was coordinated with the City of Tempe, Arizona. An asphalt concrete mixture
designated as Type C-3/4 base and surface course was selected for paving on Evergreen Drive
located east of the Loop 101 and north of University Drive in Tempe, Arizona. The designated
road section had two asphalt mixtures: a control mix with no fibers, and a mixture that contained
one pound of fibers per ton of mix. The fibers were a blend of polypropylene and aramid. The
addition of fibers was done at a batch asphalt plant in Phoenix..Basically, no repair work was done and the 2-inch overlay was placed on a much-deteriorated section of Evergreen Drive. Only the edge of the pavement was milled off to match the final overlay grade of the curb. Test sections with and without fibers were staggered on the road to allow for direct field performance comparisons considering traffic flow
and loading types (e.g., bus lanes). About 1500 lbs of each mixture were brought back to Arizona
State University (ASU) laboratories. Sample preparation included compaction of 150 mm
diameter gyratory specimens for triaxial testing. In addition, beam specimens were prepared and
compacted according to AASHTO TP8 test protocols . The performance of both mixtures
was assessed using the advanced material characterization tests that included: triaxial shear
strength, dynamic modulus, repeated load for permanent deformation characterization, flexural
beam tests for fatigue, C* line integral for fracture energy and crack propagation, and indirect
diametral tensile test for thermal cracking evaluation.


TEST RESULTS AND ANALYSES
Triaxial Shear Strength Tests
The triaxial shear strength test has been recognized as the standard test for determining
the strength of materials for over 50 years. The results from these tests provide a fundamental
basis which can be used in analyzing the stability of asphalt mixtures. This is because the
stresses acting on the laboratory specimen during the test simulate the state of stresses existing
 in the pavement, provided certain specimen boundary and geometry
conditions are met.
