scope:

This standard practice describes the testing required to determine the sealant grade (SG) of a hot-poured asphalt crack sealant according to MP 25, Table 1. It presents two approaches. In the first, the SG of an unknown hot-poured asphalt crack sealant is determined. In the second, the nominal SG of a hot-poured asphalt crack sealant is verified. It also provides an estimate of the time required to complete a single test sequence.

This standard practice may involve hazardous material, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practice and determine the applicability of regulatory limitations prior to use.
