Nity reasonably well, there are a number of limitations with this Although theĪASHTO 1993 Guide has served the pavement design commu. Transportation agencies (39) utilize the AASHTO Guide for theĭesign of Pavement Structures (AASHTO 1993).

Finally, general recommendations for an SCDOT MEPDG implementation strategy are proposed.Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Sensitivity analyses were performed to see how typical SCDOT flexible and rigid pavement structures are influenced by changes in selected input parameters. The purpose of this review was to gain insights into MEPDG implementation strategies undertaken or planned at other agencies. A literature review including a review of other state highway agency's MEPDG activities is presented. An overview of the MEPDG design features, input requirements, and distress prediction models are presented.

The MEPDG presents a major shift in pavement design strategy and full implementation of the program will require significant time and resources. This report summarizes a research effort undertaken to assist the South Carolina Department of Transportation (SCDOT) with the development of an implementation strategy that will ultimately allow the SCDOT to take advantage of the advanced pavement design procedures incorporated in the MEPDG software. The Mechanistic-Empirical Pavement Design Guide (MEPDG) provides the highway pavement design community with a new program for the design of flexible and rigid pavement structures using state-of-the-art mechanistic-empirical analyses and performance predictions.
