rap asphalt mixing plants

Premix of RAP: The patented mixer(patent no. 201110063817.X) is for mixing of heated RA with recycling agents in homogeneity. The viscosity of bitumen will decrease after the mixing so that the 2nd mixing with virgin aggregate and bitumen will me more effective. This method will reduce the mixing time of 2nd mixing(the mixing time is the same as the time of normal asphalt). It increases the quality of asphalt without sacrificing the capacity of mixing facility, increase the quality of asphalt without sacrificing the capacity of mixing facility.
