AASHTO R 78-16 (2020) PDF Download

AASHTO R 78-16 (2020) is a standard practice that provides guidelines for the recovery of residue from emulsified asphalt using low-temperature evaporative techniques. This standard specifically applies to emulsified asphalts specified in AASHTO M 140 and M 208. The two methods described in the standard are designed to simulate pavement conditions and ensure accurate recovery of the asphalt residue. The recovered residue can then be used for further testing as necessary. It is worth noting that AASHTO R 78-16 (2020) is the updated version of a previously designated provisional standard, PP 72.
