The method of mix proportion design of warm-recycled asphalt mixture used in this paper was Marshall test method.Under the premise of AC-13C grading type,the mix proportion design of mineral mixture was firstly carried out by planning solution;Then the Relative Volume Density,Porosity,Material Voidage,Saturation,Stability and Flow Value of warm-recycled asphalt mixture were measured and calculated.Through the calculation we determined that the optimum oil-rock ratio of warm-recycled asphalt mixture with 30%old materials was 4.78%;the test data of indoor road performance showed that the warm-re...
