| In recent years, our country developing rapidly, the expansion of mountainous city makes highway extending continuously. But for technical and local conditions and various external factors limit and influence, after the completion of the mountainous highway, it would meet some problems, such as rut, hug bag and goes harms. Therefore, developing the theoretical and experimental research of formation of disease and put forward the prevention measures is very important to alleviate and solve these plant disease occurrence.The subject is from the urgent need of actual project. Combining Cheng De local road project, use ANSYS to establish the finite element model and research the pavement structure mechanical response in conditions of loads and longitudinal angle. Use BISAR software to research the influence of pavement structure shear stress by Interlayer contact conditions. Research the performance and the application effect of anti-rutting agent by experiments. The main purposes are as follow:1. Using ANSYS to establish the finite element model, consider highway longitudinal angle, overloaded vehicles, automobile braking force and speed, and other factors, and make numerical analysis of this model.2. Using BISAR computing program, calculating the shearing stress of pavement structure layer under the condition of different loads and contact state between different layers and summarize.3. Making experiments of asphalt mixture which add anti-rutting agent, get the effect of anti-rutting agent in resistance to water damage performance and high temperature stability for the asphalt mixture, determine the feasibility of adding anti-rutting agent. |
