A MECHANICS-BASED PREDICTION MODEL FOR THERMAL CRACKING OF ASPHALTIC CONCRETE PAVEMENTS (WITH DISCUSSION)

The purpose of this paper is to describe the new mechanics-based thermal cracking performance model developed as part of the SHRP A-005 contract. The thermal cracking performance model predicts the amount (or frequency) of thermal cracking as a function of time. Imputs to the model include: the fundamental properties (master creep compliance curve and failure limits as a function of temperature) obtained from the new SHRP mixture test, pavement structure, and site-specific weather data. The calibrated model can be used to establish performance-based specification limits on the basis of material properties or parameters determined from the new mixture test. Conversely, the measured material properties can be used in the model to determine whether or not a particular mixture will meet specific thermal cracking performance requirements. Thus, this system provides the basis for development of a true performance-based mixture specification for thermal cracking.
