Study on High-Temperature Property Parameters of Polymer Modified Bitumen Based on Rheology

Abstract

This paper investigates the evaluating parameters on high temperature performance of polymer modified bitumen (PmB). Six bitumen were adopted in this paper and its high temperature performance was researched by rheology method and phenomenology method. Softening point, rutting factor G*/sin () and non-recovery creep compliance Jnr are tested and the mutual relationship is analyzed. Results indicated Jnr is better than rutting factor for evaluating high temperature performance of PmB.
