A PRACTICAL METHOD FOR MEASURING THE RESILIENT MODULUS OF ASPHALT-TREATED MIXES

A NEW METHOD IS PRESENTED FOR DETERMINING THE RESILIENT MODULUS OF ASPHALT-TREATED MIXES. IT IS LOW IN COST AND IS MORE RAPID THAN THE CURRENTLY USED ROUTINE STABILITY TESTS. VALIDITY OF THE METHOD IS SUPPORTED BY ITS REASONABLE AGREEMENT WITH THE RESILIENT MODULUS VALUES DETERMINED BY DIRECT RESILIENT MODULUS TENSILE MEASUREMENTS ON A VARIETY OF POLYMERIC SAMPLES. EVEN WHEN A RELATIVELY WIDE RANGE OF VALUES IS ASSUMED FOR POISSON'S RATIO, THE DIAMETRAL METHOD GIVES RESILIENT MODULUS VALUES WITHIN 25 PERCENT OF THE VALUES FOUND BY DIRECT MEASUREMENT OF THE TENSILE OR COMPRESSIVE RESILIENT MODULUS ON ASPHALT CONCRETE MIXES. RESILIENT MODULUS VALUES DETERMINED FLEXURALLY AGREE ALMOST AS WELL. THE USEFULNESS OF THE METHOD IN DESIGNING ASPHALT-TREATED MIXES FOR OPTIMUM RESILIENT MODULUS IS SHOWN BY AN EXAMPLE OF A MIX DESIGN RELATING ASPHALT CONTENT TO THE RESILIENT MODULUS. /AUTHOR/
