A BITUMEN TEST DATA CHART FOR SHOWING THE EFFECT OF TEMPERATURE ON THE MECHANICAL BEHAVIOR OF ASPHALTIC BITUMENS

A CHART HAS BEEN DEVELOPED FOR PLOTTING THE RESULTS OF STANDARD LABORATORY TESTS ON BITUMEN AGAINST TEMPERATURE, WHICH CAN BE USED FOR: (1) DISTINGUISHING BETWEEN DIFFERENT TYPES OF BITUMEN AND OBTAINING A MORE COMPLETE UNDERSTANDING OF THEIR BEHAVIOR, (2) ESTIMATING WHETHER CERTAIN PERFORMANCE REQUIREMENTS WILL BE MET, (3) CHECKING THE MUTUAL CONSISTENCY OF TEST DATA SO THAT ERRONEOUS RESULTS MAY BE DISCARDRD, AND (4) APPRAISING THE DATA USED FOR ENTERING VAN DER POEL'S STIFFNESS NOMOGRAPH. /A/RRL/
