Full Description

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.
