Executive Summary

 This study is to propose a method for evaluation of stripping resistance of stripped asphalt mixture. Two kinds of experiment on the method were performed in this paper. In the first experiment, the change of mechanical properties of asphalt mixtures in the process of moisture damage was evaluated to determine the mechanical index for evaluation of the stripping resistance. In the second experiment, moisture damaged mixture and no moisture damaged mixture were evaluated by ASTM D4867/D4868M-04 to clarify whether the difference of deterioration trend between moisture damaged mixture and no moisture damaged mixture can be observed by the test method. Two main conclusions were shown in the following.
1) It was shown that indirect tensile strength at temperature of 25℃ was the suitable
 index for evaluating the change of mechanical property in the process of moisture
 damage.
2) The difference of deterioration trend between moisture damaged mixture and no
  moisture damaged mixture could be identified by ASTM D4867/4868M-04.
