Abstract

For the problem about generating a large amount of smoke, poor environmental friendliness, asphalt aging when preparing rubber powder modified asphalt in high temperature environments, the study of warm mixed tire rubber powder composite modified asphalt mixing agent and the influence of the high and low temperature performance of asphalt mixture, the automobile tires, tire rubber powder preparation add asphalt quality were 5%, 7.5%, 10% respectively temperature mixing agent made of different dosage of warm mix rubber powder modified asphalt. Through dynamic shear rheological test (DSR), bending beam rheological test (BBR) tests to evaluate the temperature with high and low temperature performance of rubber powder modified asphalt. Experimental results show that temperature mixing agent made of waste tire rubber powder composite modified asphalt complex modulus and creep rate increases, phase Angle and creep stiffness modulus decreased, shows that temperature mixing agent has a beneficial effect on the high temperature performance, and can make its low temperature performance is obviously improved, when the temperature mixing agent is 7.5% the above effect the most obvious, but the higher dose (10%) or lower (5%), the effect will be dropped.
