Abstract:
Fatigue cracking due to repeated traffic loading is one of the major types of distress in asphalt concrete pavements. Propagation of fatigue cracks in the asphalt layer will eventually allow water to come into the pavement system, and cause deterioration of pavement structure which reduces its serviceability. Hence, description and prediction of fatigue resistance of hot mix asphalt (HMA) in an accurate manner is extremely important to flexible pavement design and preservation. In this presentation, to predict the fatigue life of the pavements, a failure criterion for the simplified viscoelastic continuum damage (S-VECD) model, referred to here as GR method, is introduced. This failure criterion found to exist in both reclaimed asphalt pavement (RAP) and non-RAP mixtures and also found to be independent of the mode of loading, strain/stress amplitude, and temperature and also is effective in accurately predicting the fatigue life of the mixtures.
