A calibrated mechanics-based model for top-down cracking of asphalt pavements Academic Article

abstract

• 2019 Elsevier Ltd A calibrated mechanistic-empirical model was developed to analyze top-down cracking (TDC) performance with actual traffic load and thermal stress. The traffic-induced and thermal-induced J-integral were employed in the Paris law with fracture parameters A and n estimated using asphalt mixture properties. Number of days for initiated TDC to reach the medium severity level was then calculated mechanistically, which was related to field performance for calibration purposes. It was observed that when TDC reached a critical length, the TDC length diminished and area of fatigue cracking increased. An associated computer program was also developed, which normally completed a 30-year performance analysis within 1 min.
