Description / Abstract:
This standard practice describes the testing required to
determine the performance grade (PG) of an asphalt binder according
to M 320, Table 1. It presents two approaches. In the first, the PG
of an unknown asphalt binder is determined. In the second, the
nominal PG of an asphalt binder is verified. It also provides an
estimate of the time required to complete a single test
sequence.
This standard practice may involve hazardous materials,
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 practices and determine the
applicability of regulatory limitations prior to use.
