Conditions of elastic recovery were explored and optimized to evaluate the properties of high performance modified asphalts effectively. The results show that it is not obvious to change the hold time or elongation of the high performance modified asphalts while it is obvious to change test temperature. SBS content of high performance modified asphalts has a slight influence on elastic recovery at 25℃ but it becomes obvious at 5℃. The results accord with those from repeated creep recovery test. So evaluation of high performance modified asphalts is suggested to be carried out at 5℃.
