Guidance for M-E Pavement Design Implementation

The goal of this research was to assess current Alabama Department of Transportation (ALDOT) practice relative to the requirements of the Mechanistic-Empirical Pavement Design Guide (MEPDG) and make recommendations as to the necessary resources, testing procedures, testing equipment and training that will be required to implement the MEPDG. To meet this goal, the MEPDG required inputs were first catalogued. Detailed information regarding each required input was gathered. The inputs were divided according to the MEPDG architecture that included: General information; Traffic; Climate; and Material properties. After the MEPDG has been catalogued, meetings were held with groups at ALDOT responsible for generating data and conducting design in the existing pavement design framework (1993 AASHTO). These meetings established a detailed knowledge of how design is currently conducted within ALDOT and what tests/practices/data sets are currently in place that can be used for MEPDG design. This information was then integrated within the MEPDG framework to identify areas ready for MEPDG implementation versus areas requiring new sets of tests/practices/data. Recommendations are made regarding items that may benefit from further study prior to full implementation of the MEPDG within ALDOT. One part of this effort was to create a web-based MEPDG program that can be used as a training and updateable on-line resource. Finally, an implementation plan was developed that provides an overall plan with sub-projects identified needing further research for full implementation.
