Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   The project will provide a means for mapping the Long-Term Pavement Performance (LTPP) defined distresses to the Federal Highway Administration (FHWA) Rule. We have assumed that the distress definitions will be those identified in the Highway Performance Monitoring System (HPMS). This mapping will be documented in the final report.The project will perform a review of the performance measure as defined in the FHWA Rule.As part of the review, any recommended revisions to the performance measure will be identified in the final report.The project will develop an estimate of error in the performance measure associated with traditional approaches to performance modeling as performed for typical pavement management processes.This portion of the project will illustrate how the Mechanistic-Empirical Pavement Design Guide (MEPDG) software may be useful in pavement management processes. The use of the MEPDG will be documented in the final report along with the estimated error. The final report will include a set of guidelines for using the error estimate in performing a risk analysis. These guidelines will describe for the reader how to incorporate this sort of error within a larger risk analysis to be performed by the State department of transportation (DOT) as part of the development of the Transportation Asset Management Plan (TAMP) as required by the Moving Ahead for Progress in the 21st Century (MAP-21) Act.This project will expand understanding of how the performance measure performs over time and with respect to various repair strategies.It will provide a level of comfort to both the FHWA and the State DOTs associated with the performance measure and how that measure may be expected to perform over time. Advancement of knowledge may be required in developing improvements to the performance measure. It would be anticipated this advancement could be undertaken through additional applied research.The estimated error associated with performance modeling of the performance measure may be used to better understand the risks associated with typical budgeting processes.The error term would identify a general estimate of error for the performance models developed. Each State DOT would be able to refine the error term for the pavements within their jurisdiction. This refinement would require additional work by the State DOT. However, this project will provide a guideline for the DOT to perform that effort.
