Rubberized Asphalt

September 28, 2010

Rubberized asphalt has been used on roads in Arizona for decades because of its high durability. It
consists of regular asphalt paving mixed with crumb rubber -- ground, used tires that would otherwise be discarded
or take up space in landfills.

While originally used because of its durability and to help dispose of used tires, rubberized asphalt has recently garnered interest for its ability to reduce road noise. Tests are underway in several parts of the country to determine whether this paving material can stand up in northern climates like Colorado and Washington.
