Evaluation of Rheological Properties of TLA and High Polymer Asphalt by DSR

Abstract

In this study the high polymer materials and Trinidad lake asphalt are used as a modifier mixed by a specific proportion of base asphalt AC-20. There are modified asphalt, containing viscosity, penetration degree, ductility, softening point and film aging tests in this study. We get the values of temperature scanning, creep scanning and frequency scanning by Dynamic shear rheometer. These values are used to assess the rheological characteristics of a variety of modified asphalt. Thus they provide various reference materials on the pavement.
