摘要：To analyze the transverse flow deformation of asphalt mixture rutting, a rutting test based on fiber Bragg grating (FBG) technology was designed, and the development rule of the transverse strain on the surface of the asphalt mixture beside the rut was studied. The results show that using FBG to study the transverse flow deformation of asphalt mixture in rutting is feasible. With the increase of the loading cycle number, the transverse strains at the test points on the surface of the specimen increase gradually. The development trends of the transverse strain at test points are the same, but their change rates are different. The transverse flow deformation of asphalt mixture with 15% waste rubber powder is slower than those with 18% and 0% waste rubber powder. The ability of AC-13C asphalt mixture with waste rubber powder resisting to transverse flow deformation is superior to that of AC-13F mixture at high temperature. With the combined modification of the waste rubber powder and the anti-rutting agent, the internal transverse flow of the asphalt mixture is relieved to a great extent. The development rule of the lateral strain can reflect the ability of asphalt mixture to resist indirect transmission of the wheel load and the flow of aggregates at high temperature, and it can interpret the development rule of asphalt pavement flow rutting. © 2018, Editorial Department of Journal of Southeast University.
