EFFECT OF MODIFIED RECLAIMED RUBBER AND GROUND VULCANIZED RUBBER ON THE PHYSICAL PROPERTIES OF BITUMINOUS PAVEMENTS WAS EVALUATED BY THE GYRATORY TESTING MACHINES /ABRIDGEMENT/
THE PURPOSE OF THIS RESEARCH WAS TO DEVELOP A REALISTIC MODEL OF FIELD CONDITIONS FOR AN ASPHALTIC CONCRETE PAVEMENT. A GYRATORY TESTING MACHINE (GTM) WAS MODIFIED AND PROGRAMMED TO IMPART CYCLIC LEADING AT TEMPERATURES ENCOUNTERED DURING HOT COMPACTION AND UNDER TRAFFIC. SHEAR TESTS, DYNAMIC RECOVERY, AND PRANDTL BEARING RESISTANCE ARE DISCUSSED. RUBBER TREATED MIXES WERE CONSISTENTLY FOUND TO SHOW GREATER RESISTANCE TO DENSIFICATION THAN UNTREATED MIXES.
