Abstract

The use of crumb rubber modifiers (CRM) in asphalt pavements is evaluated. Two different processes for adding CRM to hot asphalt mix were examined: the wet and the dry process. Performance-related properties of asphalt rubber were determined using test methods recommended by the Strategic Highway Research Program (SHRP): resistance against rutting, fatigue cracking and low temperature cracking. Results indicate that performance based grades of asphalt rubbers increased with the addition of crumb rubber when compared to control asphalt grade.
