Incorporating Pavement Preservation into the MEPDG

Pavement preservation provides a means for maintaining and improving the functional condition of an existing highway system and slowing deterioration. Although pavement preservation is not expected to substantially increase structural capacity, it generally leads to improved pavement performance and longer service life and, therefore, should be considered in the pavement design process. The American Association of State Highway & Transportation Officials (AASHTO) interim edition of the Mechanistic-Empirical Pavement Design Guide Manual of Practice (MEPDG) and related software (see Special Notes A and B) developed under the National Cooperative Highway Research Program (NCHRP) provides methodologies for the analysis and performance prediction of different types of flexible and rigid pavements. However, these methodologies and related performance prediction models focus on new design and structural rehabilitation and do not explicitly consider the contributions of pavement preservation treatments to the overall pavement performance. There is a need to identify approaches for considering the effects of preservation on pavement performance and to develop procedures that facilitate consideration of pavement preservation treatments in the MEPDG analysis process. Such procedures will ensure that the contributions of preservation to performance and service life are appropriately considered in the analysis and design process. The objective of this research is to develop procedures for incorporating pavement preservation treatments into the MEPDG analysis process. For the purpose of this research, preservation treatments are treatments applied to preserve an existing roadway, slow future deterioration, and maintain and improve its functional condition (without substantially increasing structural capacity).
