Abstract

Based on temperature field analysis and laboratory material tests of pavement, the rational simulation model and method considering consecutive temperature variance is developed with ABAUQS to study the effect of exterior factors (temperature and load) on rutting of pavement and to analyze the behavior of rutting under different temperature and loading. The results show that, (1)the rutting analysis close to the field condition can be simulated using the simulation method considering consecutive temperature variation; (2)rutting usually occurs at the average daily air temperature of 20℃ or higher, and the higher the average daily air temperature, the longer the time with the potential of rutting occurrence; (3)under the same temperature condition and accumulated loading time, rutting depth increases roughly linearly with the increasing contact pressure, while the increase will have more chance to be nonlinear on condition of overloading; (4)through regulating traffic (especially low-speed and overloading)to avoid its appearance at the high-temperature period of time, the rutting potential will be significantly reduced.
