Project detail
Project Description:   While many researches were carried out to study the efficacy of the pavement maintenance and rehabilitation (M&R) activities, there remains a great need for improved understanding of how maintenance and rehabilitation treatments perform in series and over the pavement life.  This project aims at advancing the state of knowledge in estimating pavement performance, selecting cost-effective pavement treatment strategy, and extending the life of the pavement structure. The anticipated outcomes from this research are described as follows. (1) Developing simplified and implementable but advanced analyses techniques for:•             Establishing pavement condition classification system that accurately reflects the true pavement conditions and rates of deterioration and can be used in the determination of the optimum (most cost effective) treatment application timing. •             Studying and communicating the effects of various pavement treatment strategies on the life-cycle cost and longevity of the pavement structures.•             Assessing the roles of pavement maintenance, preservation and rehabilitation on the longevity of the pavement structures and the agency life-cycle costs.•             Estimating the remaining service life (RSL) (2 and 3) and the new remaining service interval (RSI) of damaged pavement sections. (2) Linking the analyses results and the pavement performance measures of the various Long-Term Pavement Performance (LTPP) test sections for widespread use by the various State highway agencies (SHAs). (3) Enhancing the selection of cost-effective series of pavement maintenance, preservation, and rehabilitation actions (the long-term (lifecycle) pavement treatment strategy) that are needed over the life of the pavement systems to maximize their longevity.
Goals:  
The objectives of this research are:
 
(1) Advance the development of pavement performance measures to classify the various pavement sections relative to their condition states.
(2) Estimate future pavement conditions.
(3) Evaluate the effectiveness of pavement maintenance and rehabilitation treatments.
(4) Analyze the role of pavement treatment strategies in increasing the cost effectiveness of pavement treatments and extending the pavement life.
Background Information:   This project resulted from a Long-Term Pavement Performance (LTPP) data analysis Broad Agency Announcement (BAA) request for proposal (RFP). The objective of the BAA contract is to derive useable and useful interim advances, with immediate applications in the areas of pavement design, construction, and evaluation practice, through analysis of the data available in the LTPP program. The intended scope of individual projects is to conduct LTPP data analysis that support achievement of the analysis objectives set forth in the Strategic Plan for Long-Term Pavement Performance Data Analysis. The document is posted at http://www.fhwa.dot.gov/research/tfhrc/programs/infrastructure/pavements/ltpp/analysis.cfm, under Expanded Strategic Plan.

Expected Benefits:   The outcomes in this research shall advance the state of knowledge in estimating pavement performance, selecting cost-effective pavement treatment strategy, and extending the life of the pavement structure. Such innovations include: (1) Developing simplified and implementable but advanced analyses techniques for: Establishing pavement condition classification system that accurately reflects the true pavement conditions and rates of deterioration and can be used in the determination of the optimum (most cost effective) treatment application timing. Existing procedures use performance measures, such as the International Roughness Index, to classify the pavements conditions as good, fair, or poor based on the distress data only. The true condition state is a function of the pavement condition and rates of deterioration. Studying and communicating the effects of various pavement treatment strategies on the life-cycle cost and longevity of the pavement structures. Assessing the roles of pavement maintenance, preservation, and rehabilitation on the longevity of the pavement structures and the agency life-cycle costs. Estimating the remaining service life (RSL) (2 and 3) and the new remaining service interval (RSI) of damaged pavement sections. (2) Linking the analyses results and the pavement performance measures of the various Long-Term Pavement Performance (LTPP) test sections for widespread use by the various State highway agencies (SHAs). (3) Enhancing the selection of cost-effective series of pavement maintenance, preservation, and rehabilitation actions (the long-term (lifecycle) pavement treatment strategy) that are needed over the life of the pavement systems to maximize their longevity. (4) Improving intra-agency communication to provide better support for accurate and cost-effective decisions.
