AASHTO PP 85-18 (2021) PDF Download

AASHTO PP 85-18 (2021) is a standard practice that focuses on the grading or verification of the sealant grade (SG) of a hot-poured asphalt crack sealant. The standard outlines the necessary testing procedures and requirements to determine the SG of the sealant according to the specifications provided in MP 25, Table 1.

The standard presents two distinct approaches. The first approach involves determining the SG of an unknown hot-poured asphalt crack sealant, which is particularly useful when the SG of the sealant is unknown or needs to be revalidated. The second approach focuses on verifying the nominal SG of a hot-poured asphalt crack sealant, ensuring that it meets the specified requirements.

Additionally, the standard provides an estimation of the time required to complete a single test sequence, which can assist in planning and scheduling the testing process.
