Rubber-Modified Asphalt: Why Economics, Not the Environment, Drives Scrap-Tire Adoption


Rubber Modified Asphalt

Rubber-modified asphalt (RMA) is not a new concept, but its adoption still lags its environmental promise. At the recent Tire Recycling Conference in Denver, industry experts said the environmental case alone is not enough — economics and performance must carry the argument.

RMA blends crumb rubber ground from end-of-life tires into the asphalt binder, turning a steady scrap-tire stream into a road-building material known for improved durability and longer pavement life. The barrier to broader use has been cost and specification acceptance, not a lack of environmental benefit.

The Economic Case

Panelists including Doug Carlson and Stratton Kirton of Liberty Tire Recycling, Red Clark of Asphalt Plus, Bill Buttlar of the University of Missouri, and Josh Jacobs of WAP Sustainability emphasized that RMA gains ground when agencies and contractors see lower life-cycle cost and extended service life on the balance sheet.

A Proven Market For Scrap Tires

As scrap-tire markets mature, crumb rubber for asphalt stands alongside recovered carbon black and pyrolysis oil as a high-value outlet that keeps end-of-life tires out of landfill.
