Book excerpt: Documents the construction and performance of the research study which was initiated to address section 1038(d) of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA). The project selected to demonstrate the crumb rubber process was located on Platt Canyon (SH 75) from Bowles to C470 in the Denver metropolitan area. The project was a low volume roadway and quantities of crumb rubber introduced into the mix were minimal. This was to reduce risk in terms of premature failure and Colorado's limited experience with crumb rubber. Because of this limited experience, the "dry" process was selected. The project contained four different mix designs. A mix containing 1% [20 lb/ton (10 kg/Mg)] crumb rubber, a mix containing 1 lb/ton (0.5 kg/Mg), a mix containing 3 lb/ton (1.5 kg/Mg) and a mix which contained no rubber were placed on the project.
