Abstract:Between 2002 and 2004 Caltrans built five pilot projects through its rehabilitation program that contain
specifications for rubberized asphalt concrete (RAC) overlay and include a 5-year warranty on the RAC
materials and workmanship. The overall objective of these RAC warranty pilot projects was to provide a
“level playing field” for “wet process” (rubber-modified asphalt binders produced in the field or at a
terminal) and “dry process” (CRM as an aggregate substitute) rubber-modified mixes that contain a
minimum of 15% CRM (by total mass of binder).
This report is Volume 1 of a three volume series. Volume 2 is the interim performance report, which
accompanies this report and includes performance monitoring results to date. Volume 3 will be a final
report which will be prepared by Caltrans at the completion of the 5-year performance monitoring period.
