Abstract

Research on the residual flexural strength and fatigue life of pavement cement concrete in Guang Xi region under loading-high temperature-wetting-drying cycle condition to obtain the pavement concrete fatigue strength damage and the residual life prediction model. Based on defining fatigue strength damage variable and constructing residual flexural strength model, the nonlinear mathematical equation between residual flexural strength and such parameters as number of loading, placing time in high temperature and wetting-drying environment is established. Results showed that it can better reflect the decreasing process of pavement cement concrete strength after fatigue damage. The S-N curvilinear equation and failure probability were introduced to analyze the fatigue life of pavement cement concrete, results indicated that the single logarithmic equation can be used to predict the fatigue life accurately with different probability, and it accord with the Weibull distribution. the specific double parameters in Weibull distribution function was given for pavement concrete fatigue life in this multi-field environment.
