Low Temperature Rheological and Mechanistic Characteristics of Three Different Types of Asphalt Binders
並列摘要
This Study investigates the rheological and mechanistic characteristics of unmodified, polymer modified asphalt binder and epoxy asphalt binder at low temperatures. They dynamic shear rheometer (DSR) test and lap shear strength test were conducted to examine the rheological and mechanistic properties of the three types of asphalt binders. The results indicate that the complex modulus and lap shear strength of modified asphalt binder were higher than unmodified asphalt binder. Epoxy asphalt showed the highest complex modulus at lower temperatures. The phase angle of modified asphalt binder was low, and it increased slightly with the increasing temperature. The results of lap shear testing agree with the DSR test results. The lap shear bonds method is a reliable test method for evaluating asphalt performance at low temperatures quickly.
