Nov 27, 2018 Around 80 million tons of asphalt is recycled in the US each year. Recycled hot, warm, or cold mix asphalt can be just as high or even higher quality than asphalts derived from original source materials. How does it work? The aggregates within the asphalt (rocks, sand, gravel) can be crushed up and reused while maintaining their sturdiness.

Jan 29, 2020 The asphalt recycling process separates the aggregates and the binders. Each element is recycled separately before being remixed to form recycled asphalt. It’s possible to add new materials at this stage, but a lot of recycling plants produce asphalt entirely from recycled materials. There are several advantages associated with recycling asphalt.

A recycled asphalt does not require as much resources than that of a virgin asphalt. Virgin asphalt production requires more oil, more labor, and more work hours to get done. It is for these reasons that virgin asphalts are more expensive than recycled asphalt. It is friendly to the environment. Asphalt does not decay.
