Pavement Performance Measures that Consider the Contributions of Preservation Treatments

Pavement preservation provides a means for maintaining and improving the functional condition of an existing highway system and slowing deterioration. Although pavement preservation is not expected to substantially increase structural capacity, it can lead to improved pavement performance, longer service life, and reduced life-cycle costs. However, currently used measures for quantifying pavement performance do not appropriately account for the potential performance enhancement, life extension, and cost savings resulting from applying preservation treatments at the right time. For example, pavement smoothness (or roughness) which is measured by the International Roughness Index (IRI) and widely used by highway agencies is not a good measure of the effect of many preservation treatments. There is a need to identify or develop pavement performance measures that consider the contributions of preservation to performance, service life, and life-cycle costs. Also, there is a need to prepare a guide document for the American Association of State Highway and Transportation Officials (AASHTO) consideration and adoption to facilitate the implementation of these measures by state highway agencies. This information will ensure that the contributions of preservation to performance and service life are appropriately considered and help highway agencies better assess the benefits of preservation treatments and their role in maintaining the level of service of the highway system. Incorporating these measures in asset management systems would also provide a means for selecting the appropriate preservation treatments and optimizing the allocation of resources. The objectives of this research are to (1) identify and/or develop pavement performance measures that consider the contributions of preservation to performance, service life, and life-cycle costs and (2) prepare a guide document to facilitate implementation of these measures by state highway agencies. For the purpose of this research, preservation treatments are treatments applied to preserve an existing roadway, slow future deterioration, and maintain and improve its functional condition (without substantially increasing structural capacity). Accomplishment of these objectives will require at least the following tasks. The tasks for this project are as follows: Phase I: (1) Collect and review relevant domestic and foreign literature; research findings; and information relative to performance measures and their consideration of the contributions of pavement preservation to performance, service life, and life-cycle costs. This information may be obtained from published and unpublished reports, survey of state departments of transportation (DOTs), and contacts with transportation agencies and similar public and private organizations. (2) Identify and evaluate the performance measures based on their ability to account for the potential effect of applying preservation treatments on pavement performance, service life, life-cycle costs, and other relevant factors, and recommend potential measures (either new or based on existing measures) for further consideration in this research. (3) Prepare an updated, detailed work plan for Phase II that includes a process for developing and validating the performance measures recommended in Task 2, and preparation of a guide document to facilitate implementation of these measures by state highway agencies. (4) Prepare an interim report that documents the research performed in Tasks 1 through 3. Following review of the interim report by the National Cooperative Highway Research Project (NCHRP), the research team will be required to make a presentation to the project panel. Work on Phase II of the project will not begin until the interim report is approved and the Phase II work plan is authorized by the NCHRP. The decision on proceeding with Phase II will be based on the contractor's documented justification of the updated work plan. Phase II: (5) Execute the work plan approved in Task 4. Based on the results of this work (1) develop and validate the pavement performance measures and (2) prepare the guide document for facilitating implementation of these measures. (6). Prepare a final report that documents the entire research effort. The guide document shall be prepared as a stand-alone document suitable for consideration and adoption by AASHTO.
