USING GROUND TIRE RUBBER IN HOT MIX ASPHALT PAVEMENTS. CONSTRUCTION REPORT

This report documents the development of the Colorado Department of Transportation's crumb rubber mixes and the construction of the project containing these crumb rubber mixes. This project contained 4 different mix designs. Approximately 9,000 tons of Hot Bituminous Pavement (HBP) containing crumb rubber was placed on this project. Of this 9,000 tons (8,164,800 kg) of HBP, 500 tons (453,600 kg) contained 1% [20 lb/ton (0.01 kg/kg)] crumb rubber and 500 tons (453,600 kg) contained 3 lb/ton (0.0015 kg/kg) of crumb rubber. The remaining 8,000 tons (7,257,600 kg) contained 1 lb/ton (0.0005 kg/kg). In addition 500 tons (453,600 kg) of HBP containing no rubber was placed. This project will be evaluated for 3 years. In the Fall of 1997 a final report documenting the performance of the different mixes will be written.
