New research shows that rubber-modified asphalt is a safe and smart solution

One of the many exciting and innovative uses for scrap tires is as a component of rubber modified asphalt (RMA). By taking tires that might otherwise end up in a landfill or worse, illegally dumped, RMA gives the scrap tires a new life, with benefits for all.

A new study from researchers at the University of Nevada confirms that the use of recycled tire rubber in asphalt mixtures can help absorb and retain the 6PPD-Q released by tires on the road, ultimately lowering the levels of this chemical in the environment. This study demonstrates that RMA can help improve environmental outcomes, while the tire industry proactively researches alternatives to 6PPD-Q that provide equivalent tire safety. 

Not only is RMA not a pollutant in itself, but RMA roads can actually help mitigate the effects of other sources of pollution. 

Compared to traditional asphalt, RMA doubles the lifespan of roads, reduces costs by 43% and produces 32% less CO2 emissions. For state transportation agencies, this technology means more cost effective road construction and less maintenance. And for drivers, RMA means smoother, quieter, and safer rides. 

Across the board RMA is a winner.
