Abstract: Both the load stress and thermal stress contribute to fatigue damage in concrete pavements. In this paper, using the equivalent fatigue damage principle, a simple but rational method to compute fatigue-therm al stress of concrete pavement is developed, which improves the method of reference[3] presented. This new method agrees to the fact that thermal stress affected on pavement and provides a theoretical base for pavement design considering the comprehensive influence of therm al stress and load stress.

Key words: cement concrete pavement, fatigue-thermal stress, fatigue damage
