Analysis of Effects of High Temperature on Asphalt Binder

Abstract:

The study of effects of high temperature on asphalt binder based on viscoelasticity theory will help clarify the influence mechanism of temperature on asphalt binder. Based on the theory of viscoelasticity, the Dynamic Shear Rheology test is used as study method. The objective of this study is to analyze and determine the features of asphalt binder under the effect of high temperature. Meanwhile, study subjects are AH70 asphalt, SBS modified asphalt and MAC modified asphalt. The result indicates that temperature increases have great influence on asphalt binder, which are shown by the variation of parameters quickly decrease. The relationship between temperature and such parameters as complex modulus, storage modulus, loss modulus, complex viscosity, storage viscosity, loss viscosity, rutting resistance parameter and fatigue resistance parameter can be described as regression of power function.
