Development of Iowa Pavement Analysis Techniques

The primary objective of this proposed research study is to develop an Iowa Pavement Analysis Technique (IP AT) tool for Iowa county pavement management and decision-making. Specific objectives established to achieve this primary objective include the following: (1) Find the best way to model a pavement's life time and make predictions as to when it will reach the end of its service lifetime (arrive at minimum service level); (2) Take into consideration all available data such as pavement history and structure, materials, traffic, truck volumes, local development, etc., for model development; (3) Be able to absorb and integrate condition data from multiple sources such as the Iowa Pavement Management Program (IPMP), engineering field assessments, inspector team distress evaluations, etc.; (4) Be able to compute an RSL for every paved segment and provide a miles vs. RSL tally; and (5) Develop a methodology supporting predictive and consequence analysis. A focused project management strategy is essential for successful completion of the project, with activities that include formulation of the project Technical Advisory Committee (TAC) and scope, distribution of efforts, regular consultation with TAC, and so on, to be carried out throughout the project duration. The objectives of this project will be achieved through execution of the following proposed research tasks: Task 1: Kick off TAC meeting and literature review; Task 2: Develop and execute data collection plan; Task 3: Evaluate data quality and develop a master database; Task 4: Develop Iowa county pavement performance models; Task 5: Test and evaluate the predictive and consequence analysis capabilities of Iowa county pavement performance models; Task 6: Develop a prototype of an Microsoft Excel spreadsheet-based IP AT tool; Task 7: Develop recommendations regarding implementation; Task 8: Develop a preliminary draft report for TAC review and comments; Task 9: Revise the draft report based on TAC comments and discussion; and Task 10: Final report and related presentation.
