| 摘 要： | Impacts on asphalt mixture's high temperature performance with PR series additives added by means of rutting test and Repeated Shear Test (Constant Height) (RSCH) were investigated The analytic results of the two tests show that (1) rutting test is not suitable for the high temperature performance evaluation of asphalt mixture with PR series additives added for the reason of the conflict between dynamic stability and rut depth; (2) the results of RSCH,such as K1,K2,N and γ,show very well consistency which is suitable
for the high temperature performance evaluation of asphalt mixture with PR series additives
added The results of RSCH show that asphalt mixture with PR PLAST S (PRS)
added has the best performance,the PR FLEX MODULE (PRM) one is the next and t
he original one is the worst for the high temperature anti?shear performance
