USTMA, Non-Profit to Study Benefits of Rubber-Modified Asphalt
The U.S. Tire Manufacturers Association (USTMA) is teaming up with The Ray, a non-profit proving ground for sustainable transportation technologies, to assess and compile research on the benefits of using ground tire rubber in asphalt.
"The compiled research will result in a state of knowledge report that outlines existing research and identifies data gaps in the use of ground tire rubber in rubber-modified asphalt," say USTMA officials.
"In current applications, rubber-modified asphalt helps create longer-lasting roads that crack and rut less than traditional asphalt, leading to long-term cost savings for states."
It also has been found "to be quieter and create better grip and less spray for drivers in wet weather, according to a study by the University of Arizona, and produce half the amount of tire and road wear particles as traditional pavement."
“Recycling scrap tires to create rubber-modified asphalt appears to be a cost-effective way to reduce tire and road wear particles and advance the circular economy,” says Anne Forristall Luke, president and CEO of USTMA.
