This Virginia Transportation Research Council study investigated whether stockpiling a CCPR mixture had any negative consequences with respect to the mechanical properties of the mixture. The laboratory study assessed the mechanical properties of a CCPR mixture subjected to a laboratory stockpiling procedure. The mechanical properties assessed included the indirect tensile strength and dynamic modulus of the CCPR mixture. The study recommended that VDOT consider allowing stockpiling of a CCPR mixture produced using foamed asphalt as the recycling agent and cement as the active filler for up to 24 hours, following verification of these findings from a future study that examines field stockpiling from additional projects.
