Research on Anti-rutting Performance of High Modulus Asphalt Concrete Pavement
A new way of anti-rutting was put forward by improving modulus of asphalt concrete and the effect of high modulus asphalt concrete (HMAT) on rutting was studied in view of mechanics. Starting from the mechanism of rutting, the mechanical property of HMAT and the effect of modulus of middle layer on rutting were analyzed. The dynamic stability and modulus of HMAC were analyzed by test, and the mechanical property of pavement structure and the mechanical response of high modulus pavement structure were analyzed by numerical calculation. The result show that (1) increase of the dynamic stability and modulus of HMAC help to against rutting; (2) the maximum shear stress occurs in middle layer of pavement structure according to mechanical calculation, HMAC can raise elastic modulus of middle layer. HMAC can also improve stress state of pavement structure, reduce shear strain and asphalt pavement rutting.
