[Abstract] In order to make up the deficiency of the performance evaluation method of solvent cold patching mixture and further study it, firstly, a solvent cold patching asphalt was developed by orthogonal test, then the different preparation processes of cold patching asphalt were analyzed, the performance evaluation method of cold patching mixture was proposed and optimized. Finally, the cold patching mixture made of self-developed cold patching asphalt was compared and verified with three kinds of cold patching mixture sold in the market. The results show that the best preparation process of cold patching mixture is to heat the aggregate, cold patching asphalt and mixing pot to 60 ℃ and then mix; The cold patching mixture made of self-developed cold patching asphalt has excellent low-temperature workability, high initial strength and strong water damage resistance. The proposed evaluation method can better evaluate the road performance of cold patching mixture. The performance evaluation system of cold patching mixture were improved, which can better guide the test design and construction.
