A STUDY OF VISCOSITY-GRADED ASPHALT CEMENTS

THE BUREAU OF PUBLIC ROADS HAS UNDERTAKEN A COMPREHENSIVE RESEARCH PROGRAMME DIRECTED TOWARDS USING FUNDAMENTAL KNOWLEDGE TO DEFINE THE ESSENTIAL FUNCTIONAL PROPERTIES OF ASPHALT /BITUMEN/ AND RECOMMENDING REALISTIC TESTS AND MATERIAL REQUIREMENTS FOR SPECIFICATION WRITERS. TESTS WERE MADE TO INVESTIGATE THE FEASIBILITY OF GRADING AND SPECIFYING ASPHALTS BY VISCOSITY AT 140 DEGREES F IN LIEU OF PENETRATION AT 77 DEGREES F. VISCOSITY AND TEMPERATURE RELATIONS WERE MEASURED AND A DISCUSSION OF THE DUCTILITY AND DURABILITY IS MADE WITH REFERENCE TO THE SHEAR SUSCEPTIBILITY. /RRL/
