Rubber concrete roads

In June 2003, a section of rubber concrete (29.5 kg per cubic metre) roadway at a major intersection in the city of Cottonwood, Arizona (cold climate), was constructed by ADOT. The thickness for controlled concrete design was 23 cm. But for the purpose of testing the performance of rubber concrete, the thickness was reduced to 13 cm. In December 2003, ADOT built a second major road (29.5 kg per cubic metre and a small volume of fibres) in Sunland Gin near Tucson, Arizona (warm climate). There are about one dozen rubber concrete structures that have been built here and there in Arizona, and they so far are performing well.
