This test method covers the determination of the tack coat adhesion quality as measured by the tensile strength of tack coat materials on the free surface of asphalt pavement in the field or laboratory. This test can be performed in the field on the surface of asphalt pavement or on 150-mm (6-in.) diameter@ gyratory-compacted samples. This standard may involve hazardous materials@ operations@ and equipment. This standard does not purport to address all safety concerns associated with its use. It is the responsibility of the user of this procedure to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
