Influence of RAP Content on Pavement Performance of Hot Plant Recycling Asphalt Mixture
In this paper, the influence of RAP content on pavement performance of hot plant recycling asphalt mixture is experimentally studied. The pavement performances contain high temperature stability, low temperature stability, water stability and fatigue resistance. Recovered asphalt was firstly extracted from RAP, and the properties of recovered asphalt was then tested and compared to normal 70# pavement asphalt. The gradation of recovered aggregate and new aggregate was then tested, and the mine material mixture gradation was determined. Marshall Test was adopted to determine the optimal asphalt content. The pavement performances show that the dynamic stability increases with RAP content increasing. The blending strain and fatigue life decreases while the stiffness modulus increases with the RAP content increasing. However, the residual stability and TSR show no obviously change with RAP content increasing.
