2208 - Development and Implementation of a Mechanistic and Empirical Pavement Design Guide (MEPDG) for Rigid Pavements - Phase 3

The Mechanistic-Empirical Pavement Design Guide (MEPDG) is the new pavement design guide released by the American Association of State Highway and Transportation Officials (AASHTO). AASHTO suggests each state highway agency validates and, if necessary, calibrates the MEPDG design models based on local conditions. The Oklahoma Department of Transportation (ODOT) is currently under the process of accepting the MEPDG to replace the 1993 design guide. In the first two phases of this project, a comprehensive research work has been carried out which involved laboratory tests, road section instrumentation and sensitivity analysis. The research revealed valuable information regarding local climate data, concrete material properties, and the performance data of Oklahoma rigid pavements. In view of other states' experience, it would be beneficial for Oklahoma to extend the State Planning and Research (SP&R) 2208 project to a Phase 3 that focuses on the local validation/calibration of the MEPDG for Oklahoma rigid pavements and also addresses the uncertainty in the slab/base friction property. The primary objective of Phase 3 is to validate and calibrate the MEPDG for the design of typical Oklahoma rigid pavements. The secondary objectives of the proposed research are (1) to continue to monitor the field performance of the instrumented road section on I-44 and (2) to investigate the slab/base friction property of typical Oklahoma rigid pavement structures.
