Abstract After defining fatigue damage variable and constructing residual flexural strength damage model,nonlinear mathematical equations of residual flexural strength and parameters,such as number of loads andfunction time in low temperature and dry environment,were established to research residual flexural strength and fatigue life of cement concrete pavement in northern cold regions under low-loading and temperature-drying conditions, to identify mechanism of fatigue damage in concrete pavements and residual life prediction model, and to verify accuracy of the model through experiments.These equations can better reflect lawsgoverning mechanical property damage of concrete pavements after fatigue. S-N fatigue life curvilinear equation and failure probability were introduced to analyze fatigue life of concrete pavements. Results indicated that the single logarithmic equation can be used to predict fatigue life of concretes with different failure probabilities, and in this case, fatigue life curve conforms to Weibull distribution function. This paper also provides specific double-parameter Weibull distribution function under loading-low temperature-drying conditions.
