Abstract：In view of the phenomena that ordinary asphalt has such as softening or cracking under extreme temperature conditions，this study proposed a rubber asphalt concrete performance analysis scheme.In order to verify the basic properties of the material，the optimum ratio of the material，selected by three-factor and three-level orthogonal test，turned out to be 25% for 80 mesh powder.The performance analysis of the material was completed by using the mix ratio design.The analysis resulted showed that AR-AC-13 was more suitable for the repair work of municipal road asphalt surface.When the material was used in the construction of municipal roads，the asphalt pavement of municipal roads had good cracking resistance.The rubber powder contained in it had good adsorption performance for base asphalt，which could prolong the service life of municipal roads to the maximum extent.
