Prediction of Low-Temperature and Thermal-Fatigue Cracking in Flexible Pavements
A system was developed to predict the amount of temperature cracking in asphalt concrete surfaces throughout their service lives using laboratory materials data and available weather information. Basically, four models were developed to form the system. In brief, the models are as follows: Model 1 - Simulation of bituminous pavement temperatures. Model 2 -(i) Estimation of asphalt concrete stiffness as a function of temperature and loading time. (ii) Prediction of in-service aging of asphalt. (iii) Estimation of thermal stresses. Model 3 - Prediction of low-temperature cracking. Model 4 - Prediction of thermal-fatigue cracking. The consideration of thermal-fatigue cracking (Model IV) due to daily temperature cycling makes the system an improvement over other available techniques in this field.
