In this paper, the pavement performance of recycled hot mix asphalt with 30% recycled asphalt pavement (RAP) content is studied by mix design, splitting test, freeze-thaw splitting test and dynamic modulus test. The results show that the recycled hot mix asphalt with 30% RAP content has better high-temperature deformation resistance than hot mix asphalt, but low temperature performance is slightly worse, and the water stability is not much different. It is proved that the road performance of recycled hot mix asphalt with 30% RAP content is the same as that of hot mix asphalt. Recycled hot mix asphalt with 30% RAP content can be widely used. The flexural creep test data at different temperatures were fitted to the exponential decay function, which proved that the recycled hot mix asphalt conformed to the generalized Maxwell model, and provided parameters for the establishment and analysis of the viscoelastic mechanical model of the recycled hot mix asphalt.
