Researchers are now incorporating the lat- est advances in pavement design into the new Mechanistic-Empirical Pavement Design Guide (MEPDG),developed under the National Cooperative Highway Research Program (NCHRP) 1-37A project and adopted and published by AASHTO. The goal of the Mechanistic-Empirical Pavement Design Guide (MEPDG) is to identify the physical causes of stresses in pavement structures and calibrate them with observed pavement performance. MEPDG is an excellent product and major enhancement to current technology; however the technology is still evolving: Do not expect perfect predictions Need to locally calibrate to actual field performance Must be prepared to Conduct Trench Sections!!!!!

MEPDG includes two models for Levels 2 and 3 hot-mix asphalt (HMA) dynamic modulus (E *) predictions.The two models are NCHRP 1-37A and NCHRP 1-40D.
