The Virginia Transportation Research Council performed a laboratory investigation to evaluate whether stockpiling a CCPR mixture using foamed asphalt and cement as an active filler had any negative consequences with respect to the mechanical properties of the mixture. The mechanical properties included indirect tensile strength and dynamic modulus. The study recommended allowing stockpiling of CCPR mixtures using foamed asphalt and cement as the active filler for up to 24 hours. The study recommended verification of the findings and recommendations through follow-up studies.
