The Achievement
In 2007 the City of Chattanooga, Tenn., began implementing a new process for recycling asphalt and using it as the topcoat for repaving city streets.
The Benefits
The “greener” mixture contains up to 50% recycled asphalt product and costs approximately 20% less than new asphalt. Plus, the new mixture lasts at least 15 years, compared to 11 or 12 years for a regular mix. The production process requires less energy and heat, and the applications of cooler green asphalt reduce the generation of volatile organic compounds (VOCs) when the asphalt is put down.
