Evaluate the shear strength of tack coat between lifts of asphalt using this fixture.

 

Highway agency interest in tack coat shear strength led to research, some of which influenced Pine’s Tack Coat Bond Strength Test Fixture.

Pine’s Tack Coat Bond Strength Test Fixture accommodates 2″, 3″ 4″, and 6″ diameter specimens.  These specimens can be gyratory and Marshall specimens as well as roadway cores.

The basic fixture accommodates a 6″ specimen.  However, a proper test requires alignment of the specimen’s shear plane with the fixture’s shear gap.  Pine’s Kit for 5.5″- 6″ Specimens provides shims and bolts to fix a specimen into position for testing.

 

TESTING SMALLER SPECIMENS

 

APPLYING A FORCE NORMAL TO THE SHEAR PLANE

Apply a force normal to the the shear plane using Pine’s Normal Force Kit in conjunction with the base fixture.  The kit provides a calibrated force of 0 to approximately 100 pounds.

 

NOTE:  This fixture fits the Pine AF850T and AF850TD Test Presses.
