Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   The project approach will include an assessment of both Long-Term Pavement Performance (LTPP) and State agency performance data for the same pavement sections that have been collected by State agencies. Historical pavement performance information will be extracted from the LTPP database for selected test section locations, and the State agency data will also be evaluated for these same locations. Additionally, a record of pavement treatments is available in the maintenance and rehabilitation tables in the LTPP databases. This treatment information is very important because ultimately the consistency of the pavement management recommendation for treatment is the important measure of performance data reliability from the network level perspective. Multiple analyses of these two datasets will be performed to compare the uniformity of results. Statistical and quantitative-based comparisons will be made to demonstrate that the data meet the required level of consistency to support network-level applications. From this comparative analysis, the metrics necessary to support network-level use of the data, and the objective of providing recommendations for supporting performance-based reporting requirements, will be developed.
To provide a step forward in understanding the use of ride, rutting, and distress data in pavement management system applications, both at the State agency and national levels.
Product Type:   Data

Research report
Test Methodology:   Improvement in the ability to set interagency condition benchmarks, compatible with national needs.
Other Information:   LTPP Analysis Plan | Objective 9 | Outcome A | Project 2 | Priority High | Sequence 1
Partners:   Federal Highway Administration: Office of Research, Development, and Technology - Office of Infrastructure Research and Development; Role(s): Advisory, Technical, Other stakeholder
Expected Benefits:   The work conducted under this project will demonstrate the consistency of ride, rutting, and distress data being collected by the Long-Term Pavement Performance (LTPP) program and State transportation agencies, and the methodology for assuring that pavement management applications are supported by acceptably accurate and precise data.
Deliverables: Name: Final report and related documents.
Product Type(s): Research report, Techbrief, Data, Promotional materials
Description: Deliverables will include the sample set of distress data for Long-Term Pavement Performance (LTPP) sites, and the statistical evaluation of that data to determine limits of acceptable data variation for the proposed network-level applications. There will also be a summary of the analyses and determination of metrics produced, as well as recommendations for producing pavement asset and other network condition level reports. Products from this study will include the illustration of statistical techniques as applied to pavement ride, roughness, and distress data for the purpose of determining acceptable variation and recommendations for reporting of pavement asset condition.
