AN ADHESION TESTER FOR ROAD BINDERS. IV: BRITTLE ADHESION TEMPERATURE

The pendulum adhesion tester has been used to study the adhesion of adequately wetted chippings to a film of binder at low temperatures. Brittle failure results in the loss of 50% of the chippings some 60 deg C below the e.v.t. In the case of a coke oven tar. Greater resistance is shown by pvc tar, bitumen and most tar/bitumens. The effect of film thickness is noted and results compared with those from the fraass brittle test. /Author/TRRL/
