Research on Anti-Rutting Performance of High Modulus Asphalt Concrete Pavement

Abstract:

The new ways of anti-rutting was put forward by improving modulus of asphalt concrete and the effect of HMAT(high modulus asphalt concrete) on rutting is studied in view of mechanics; The cause of asphalt pavement track is closely related to pavement structure under load. Starting from the mechanism of rutting, the mechanical property of HMAT and the effect of modulus in middle layer on the rutting were analyzed; the dynamic stability and modulus of HMAC were analyzed by text and the result show that Increase of the dynamic stability and modulus of HMAC went against rutting; The mechanism of pavement structure was analyzed by the numerical analysis show that the maximum shear stress occurred in middle layer of pavement structure according to mechanical calculation. HMAC can raise modulus of elasticity of middle layer. HMAC can also improve stress state of pavement structure, reduce shear strain and prevent asphalt pavement track.
