Measuring, Characterizing, and Reporting Pavement Roughness of Low-Speed and Urban Roads

The objective of this research is to identify/develop a means for measuring, characterizing, and reporting pavement roughness on low-speed and urban roads.  Tasks: Phase I: (1) Collect and review relevant domestic and foreign literature; research findings; and information relative to profile measurement and characterization, reporting, and use of roughness data. This information may be obtained from published and unpublished reports, survey of state departments of transportation (DOTs), and contacts with transportation agencies and other public and private organizations involved in profile measurement. (2) Based on the review performed in Task 1, identify current and emerging profile measurement technologies, and assess their capability for measuring accurate elevation profiles at low speeds (including stoppage) and in urban settings (e.g., signalized locations, crowned intersections, sudden grade changes, and unique surface features, traffic conditions, and road geometry). (3) Based on the review performed in Task 1, identify and evaluate available means for characterizing and reporting pavement roughness for project and network levels for the conditions noted in Task 2 and recommend potential means for further evaluation/development in Phase II. (4) Based on the evaluations performed in Tasks 2 and 3, prepare an updated, detailed work plan for Phase II that includes an approach for further evaluating the potential means identified in Task 3 and developing validated means for characterizing and reporting pavement roughness on low speed and urban roadways. (5) Prepare an interim report that documents the research performed in Tasks 1 through 4. Following review of the interim report by the 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: (6) Execute the plan approved in Task 5, and develop and validate the means for characterizing and reporting pavement roughness of low speed and urban roadways. Also, describe how the pavement roughness data obtained from the developed method can be used as a measure of ride quality. (7) Recommend changes to current AASHTO standard practices to accommodate measuring, characterizing, and reporting pavement roughness on low speed and urban roadways for consideration and adoption by AASHTO, or develop new practices if necessary. Also, describe costs and benefits associated with the implementation of the new or revised practices. (8) Submit a final report that documents the entire research effort. The recommended changes to current AASHTO practices shall be prepared as a stand-alone deliverable suitable for consideration and adoption by AASHTO.
