• Abstract:
  The primary objective of this research was to identify existing historical data (i.e., climate, traffic, ; pavement design information, material properties, and pavement performance) within the SCDOT for use ; in the local calibration of the Mechanistic Empirical Pavement Design Guide (MEPDG) for South ; Carolina. Based on all of the compiled information, 20 in-service pavement sections (i.e., 14 asphalt ; concrete (AC) sections and 6 Portland cement concrete (PCC) sections) were identified as suitable for this ; study, and information gaps were identified. A comprehensive subgrade sampling and testing plan was ; developed, and field and laboratory tests were performed to study the subgrade modulus at 3 sites. The ; data collected for the 20 sections was used to perform a preliminary analysis of the MEPDG AC rutting ; models, AC fatigue cracking models, AC transverse cracking model, and the JPCP transverse cracking ; model. Level 1 (project specific), Level 2 (region specific), or Level 3 (default) inputs were used, ; depending on data availability. The preliminary calibration factors found from the analysis should not be ; used for design until further studies are performed. A plan for future phases, including the additional high ; priority, high quality data needed to complete the MEPDG analysis for the local calibration and a plan for ; special pavement test sections, is proposed.
