CHEMICAL AND PHYSICAL PROPERTIES OF ASPHALT-RUBBER MIXTURES--PHASE III, VOLUME V--EFFECT OF TEMPERATURE

This study had the objective of evaluating the effects of temperature on physical properties of asphalt-rubber mixtures. Eight different asphalt-rubber mixtures formulated with two different asphalts and two types of granulated reclaimed rubber at 20 and 25 percent concentrations were studied. These mixtures were comparable to mixtures supplied by two of the major asphalt-rubber producers. These mixtures were tested at three different temperatures--77F (25C), 39.2F (4C), and -20F (-29C). Asphalt-rubber mixtures were produced in the Torque-Fork mixer at 375F using a one hour mixing duration. Testing procedures utilized were the Schweyer Rheometer and Force-Ductility. A total of 12 measured or calculated parameters are reported and discussed. The study concluded that (1) temperature significantly influences physical properties of asphalt-rubber mixtures, (2) that mixtures made with the two rubber types and asphalts studied behave differently at different temperatures.
