SPR-4830: Moisture Control and Performance Evaluation for Asphalt-Treated Cold Recycled Pavements (CIR and FDR)

The main objective is to establish a practical method to optimize the curing process of ATCR pavements based on the measured moisture contents, and thereby to achieve desirable pavement performance. The accuracy of electrical resistance and GPR measurements for moisture content prediction will be evaluated, and a more accurate and practical method will be selected as a quality control tool. In addition, the effect of moisture content on ATCR material performance will be evaluated to determine the optimum moisture content. Consequently, this study will provide well-established protocol to determine when the ATCR pavements achieve desirable performance to be opened to traffic, based on the moisture contents.
