Determination of Optimum Time for Application of Surface Treatments to Asphalt Concrete Pavements

An extensive literature review has been performed on the surface treatment methods. Research studies that are focused on the timing of the application of treatments to asphalt concrete pavements have shown that current maintenance practice is based on the construction phase and monitoring of the performance of the treatment over time. Some of the most recent studies also address the economic issues involved in the selection process and the timing of the application of treatments.

Several test sites has been identified and documented for the implementation in the second phase of this project. Detailed work plan has been proposed in order to better understand the mechanism by which surface treatments protect the existing pavement from further aging and deterioration due to traffic and environmental loadings and to reasonably predict the optimum time for the application of these treatments.
