Terminal Blend Tire Rubber Asphalt (TBTRA)
City of Colorado Springs, Colorado
The City of Colorado Springs, Colorado is experimenting with a new pavement method, TBTRA, on select roadways. This method utilizes asphalt that uses a blend of recycled raw tire crumb rubber and SBS polymer-modified asphalt. One of the many reasons that terminally blending these materials prove to be beneficial is the process eliminates smoke and particulates from entering the atmosphere. The final product also provides better drainage on the roadways, thus reducing stormwater runoff.
The City recently selected Resource to evaluate these test areas to ascertain the useful life of the TBRTA compared to the City’s traditional dense graded asphalt pavements. Rii will present an analysis approach to incorporate the influences of all relevant variables, such as traffic volume and truck traffic, age of treatment, pavement type, pavement structure, traffic acceleration and deceleration.
