Applicability of Standard Rheological Evaluation Methods for High Content SBS Polymer Modified Asphalts

High content SBS polymer modified asphalt (HCPMA) can serve as pavements under heavy traffic and a wide range of temperatures. However, the applicability validity standard rheological evaluation methods to characterize HCPMA are still unclear. In this study, influence on conventional properties behavior was analyzed. A higher improve performance grade binder PG100-34. The slope Jnr-σ linear curves from MSCR various stress levels decreases when increases. replace Jnrdiff an indicator sensitivity. also decrease flexural creep stiffness increase rate binders. fatigue resistance parameter increases yields at strain, with increasing content. These results show that further rutting, thermal cracking, fatigue. Current should be evaluating HCPMA. tests not valid for
