BINDER PROPERTY EVALUATION OF HIGH VISCOSITY POLYMER MODIFIED ASPHALTS AND THE INFLUENCE ON MIXTURE PROPERTIES

Norihisa FURUSATO, Hiroshi ISHIKAWA, Koichi OZAWA

Improvement of high viscosity polymer modified asphalt (HVPMA) has been tried for higher durability binder and multiple applications. The present evaluation methods of HVPMA are the same methods as polymer modified asphalt type$B-6(B. However, they aren$B!G(Bt necessarily suitable to the improved HVPMA. Then, we tried to evaluate the binder properties of HVPMA by SHRP methods, and examined the influence of the binder properties on the mixture properties. There is a high correlation between the G*/sin$B&D(B of HVPMA and the Dynamic Stability of the mixture, and between the G*$B!&(Bsin$B&D(B of HVPMA and the Cantabro loss of the mixture. Therefore, the mixture properties could be predicted from the DSR tests of the binders.
