We discuss the effects of fossil fuel-consuming vehicles on the roads on the future of the world and the future of cars that run on greener fuels, but what about the highways and highways on which these vehicles travel?
Asphalt is a huge business in contemporary economy with its annual worldwide demand of 110 million tons. Until the 20th century, the majority of its production of natural asphalt made from rotten plants. Today, more than one asphalt is refined from crude oil. Asphalt currently accounts for the largest share of emissions from road construction, with 28 percent. The closest is concrete with 18 percent.
THE RISK OF THE ROADS AS WARMING UP
Pollution from asphalt may increase in the coming years due to rising temperatures. Asphalt releases harmful greenhouse gases (GHG) into the atmosphere when exposed to extreme temperatures.
On the other hand, asphalt-coated surfaces and roofs are also a risk. In US cities alone, they account for about 45 percent and 20 percent (roofs) of surfaces, respectively. 75 percent of single-family homes in Canada and the USA have asphalt tiles on their roofs. In a road-like form, asphalt shingles contain a particularly damaging oil as the primary component. Shingles does not decompose or biodegrade. The United States alone produces approximately 12 million tons of asphalt shingles scrap and suram scrap each year, of which more than 90 percent is dumped into 20 million barrels of oil equivalent and landfills.
