Initial Development of a Calibrated Mechanistic Approach and Associated Surrogate Test Protocols for HMAC Mixture Fatigue Characterization
Over the past decade, the Texas Department of Transportation (TxDOT) focused research efforts on improving hot mix asphalt concrete (HMAC) mix design to preclude rutting in the early life of pavements. However, these rut-resistant stiff mixtures may be susceptible to long-term fatigue cracking due to oxidative aging. This project completed initial development of an HMAC mixture fatigue design and analysis system and associated surrogate fatigue tests to ensure adequate mixture fatigue performance in a particular pavement structure under specific environmental and traffic loading conditions. In addition, researchers compared the fatigue resistance of commonly used TxDOT HMAC mixtures and investigated the effects of binder oxidative aging on fatigue performance.
