AN IMPACT TEST FOR ROAD BINDERS

A STUDY HAS BEEN MADE OF THE ENERGY ABSORBED IN RUPTURING A ROAD BINDER FILM IN A PENDULUM IMPACT MACHINE. AT HIGH TEMPERATURES THE ENERGY IS ABSORBED BY VISCOUS TRACTION, AT LOW TEMPERATURES BY ELASTIC STRAIN ENERGY, AND IN THE INTERMEDIATE VISCO-ELASTIC REGION THE ENERGY RISES TO A MARKED MAXIMUM PROVIDING OPTIMUM CONDITIONS FOR STONE RETENTION BY THE BINDER. A STANDARD TEST AT 10 DEGREES VALUE, UNDER CONDITIONS OF BRITTLE FRACTURE, WHICH IS DEMONSTRATED TO BE SUITABLE FOR COMPARING TARS OF KNOWN EQUIVISCOUS TEMPERATURES AND WHICH REFLECTS THE WIDTH OF THE VISCO-ELASTIC PEAK, GIVING A MEASURE OF RESISTANCE TO BRITTLE FAILURE OF THE BINDER. /AUTHOR/
