Use of Waste Tires (Crumb Rubber) on Colorado Highways

This study will evaluate the feasibility of using waste tires (crumb rubber) in the construction of asphalt pavements. As part of the evaluation, two pilot test sections and one control section will be built. The Colorado Department of Public Health and Environment provided the grant money to construct the two pilot test sections. One test section will be built with crumb rubber modified mix using the wet method and the other using the terminal blend method. Each test section will consist of 1,000 tons of 2-inch asphalt overlay. The control section will be constructed with the conventional polymer modified binder, PG 64-28, without the crumb rubber modifier. The goals of this research project are to develop Colorado-specific materials, best management practices, guidelines, and construction specifications for rubberized asphalt pavement.
