• Abstract:
  The primary focus of this research was to determine the effects of design and construction features, such as overlay ; thickness and mix type, presence of milling, and type of restoration, on pavement response and performance and to ; establish their importance in the prediction of future performances of rehabilitated pavements. Long-Term Pavement ; Performance program Specific Pavement Study (SPS)-5 and SPS-6 experiments provided information to obtain a ; better understanding of the effects of design and construction features on pavement response and performance of ; rehabilitated flexible and rigid pavements. The research findings provided guidance to identify appropriate features ; and rehabilitation alternatives for different pavement types and recommendations for improving data collection ; activities. The analyses results obtained in this study helped determine the causes of distress and helped formulate ; models for predicting performance of rehabilitated pavements. In addition, data from SPS-3 and SPS-4 experiments ; were used to determine effectiveness and timing of preventive maintenance treatments. The findings suggest that it is ; possible to determine significant differences between treatment alternatives with respect to pavement performance ; and treatment timing. Performance of rehabilitated pavement sections from SPS-5 and SPS-6 were also examined ; using the Mechanistic Empirical Pavement Design Guide and compared with the field performance.(1) The results ; provide useful information about rehabilitated pavement section performance predictions and recommendations for ; future model improvements.
