4C H A P T E R 2 This chapter summarizes the state of the practice of pavement preservation and the MEPDG design analysis process as gleaned from a literature review and interviews with SHA and industry personnel. The summary covers items of relevance to the development of approaches for considering the effects of preservation in the MEPDG procedures, including (1)

9 Most of the interviewed SHAs did not consider pavement preservation in the design procedure. However, Minnesota noted that preservation treatments probably have been applied to all pavement sections used in the development of performance models for the R-value and Mn/Pave design procedures.
