For the CCPR mixture, the foamed asphalt content was 2.2% by weight of dry RAP, and the total water content was 7.2% by weight of dry RAP. Type I/II Portland cement was added at 1.5% for both CCPR and CIR mixtures. This was higher than the suggested maximum cement content in AASHTO PP 94 but it was necessary to meet the dry ITS requirement.
