Phạm vi áp dụng / Scope of standard

This test method quantifies the tensile force needed to remove a
pull-off stub adhered to a solid substrate with asphalt binder.
Samples are prepared at controlled environmental and moisture
conditions (i.e., temperature and humidity). After conditioning, a
pneumatic load is applied to a pull-off stub using an ASTM D4541
Type IV adhesion tester until failure. The pull-off tensile
strength and mode of failure are used to describe the bonding
properties of the asphalt binder and compatibility between
aggregates and asphalt binders.

The values stated in SI units are to be regarded as the
standard.

This test 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 to establish appropriate safety and health practices
and determine the applicability of regulatory limitations prior to
use.
