Project description

The Georgia Department of Transportation (GDOT) has initiated a Georgia Long-Term Pavement Performance (GALTPP) monitoring program 1) to provide data for calibrating the prediction models in the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) and 2) to monitor sites for evaluating the effect of various materials and methods on pavement performance. A total of 38 flexible pavement sites (17 LTPP and 21 non-LTPP) and 23 rigid pavement sites (11 LTPP and 12 non-LTPP sites) sites were selected for the MEPDG calibration and various field and laboratory testing, including condition surveys in accordance with LTPP Distress Identification Manual, Falling Weight Deflectometer (FWD), etc., were conducted on the non-LTPP sites.
