Article Preview

Fiber reinforcement as an available attempt has been proved to be effective in improving the toughness of asphalt concrete and is becoming a new method for highway maintenance. When fiber modified asphalt mixture is used as the surface course of a reconstructive pavement, the interface bonding property between top and lower layers seems to become a crucial factor in the road performance of the long lasting pavement. The primary objective of the research is to study the influence of fiber inclusions on the interfacial shear property of the pavement. With the purpose of discussing the shear strength of the interface between Bonifiber modified asphalt mixture top layer and the normal asphalt mixture layer,the laboratory shear test was developed on MTS-810. Four kinds of double-layered cylindrical specimens were made to simulate the different pavement structures. Test results show that the overlaying with Bonifiber modified asphalt mixture improves not only the general road performance but also the interface property. It is concluded that, the interface property of pavement with fiber reinforced top layer behaves much better than that with normal asphalt concrete one.
