Long-Term Pavement Performance Evaluation
Hot mix asphalt (HMA) performance in terms of fatigue resistance is a well-developed area of pavement design worldwide. Different equipment is available to predict the fatigue performance due to the well supported technical background.Sophisticated pavement design methods utilises the asphalt performance to predict pavement performance and the relative performance comparison between different mix types is also feasible.The research work presented in this paperprovidesan analytical approach to validate laboratory fatigue tests and in-service pavement performance. Large diameter cores (320 mm) were taken from heavily trafficked heavy duty pavement structures and subsequently 2 point bending tests were performed on the cut specimens. The pavement response to loading derived from the FWD measurement was compared to the performance obtained from the laboratory fatigue tests andthe remaining life of the pavement structure was assessed.
