Development of Performance Models for the Rubberized Asphalt Concrete of Local Agencies in California

Rubberized asphalt concrete (RAC) pavements have exhibited better field performance than conventional hot mix asphalt (HMA) in terms of resistance to reflective cracking, durability, and lowering traffic noise. It is expected that the performance models for RAC overlays will be significantly different than those with unmodified binders; however, RAC performance models do not currently exist for most pavement management systems (PMSs). Performance data from various local agencies were used to create models that could predict performance for RAC overlays. Models used throughout the United States were reviewed and studied to find suitable models for RAC used in California. After careful comparison, the modeling approaches used by Metropolitan Transportation Commission (MTC), and Stantec were selected to be the best, for use by local agencies. By using the data from San Francisco Bay Area, Southern California, and the California Central Valley region, RAC performance models were developed for the MTC pavement management program and the Stantec pavement management models, respectively.
