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
