Design of Asphalt Pavements for Thermal Fatique Cracking
This report describes the development of a design procedure for asphalt pavements to resist thermal fatigue cracking. The first step is the development of a computer model based on fracture mechanics for predicting transverse cracking due to thermal fatigue cracking in asphalt concrete pavements. The effectiveness of the model developed is demonstrated by comparing its results with field data from Michigan. The design equation is developed by regression analysis of the results of 576 separate runs of the computer model for a variety of climatic conditions. The design procedure is automated, using a computerized pattern search routine to select the best combination of asphalt concrete thickness, bitumen and mix properties to withstand thermal fatigue for a specified period of time in a specified climate.
