A new composite modified asphalt material is proposed in this paper in order to improve the utilization in the RAP regeneration process, and ensure the regenerated asphalt mixture can meet the road conditions.Buton Rock Asphalt（BRA）,E-44 thermoset epoxy resin,curing agent,70#ashpalt and RAP are the main materials for this test. The composite modified regenerated asphalt mixture is made of a certain proportion of the above materials. And the road performance under different dosing modifiers are evaluated by high temperature rutting test,low temperature bending test,Marshall test,four point bending beam test.Response surface method is used to design test and predictive results.The result shows: The high temperature performance of the regenerated asphalt mixture can be improved by the BRA and epoxy resin.With the addition of rock asphalt, the flexibility of the regenerative asphalt mixture is lowered.It means the ability of the mixture release stress is deteriorated.It can be improved by adding epoxy resins.The regenerative asphalt mixture is made into an irreversible solid material through the cross-linking curing reaction of BRA,epoxy resin and curing agent. The requirements for RAP can be reduced and the utilization rate of RAP can be increased.
