Optimization of and Maximizing the Benefits from Pavement Management Data Collection

项目名称：	Optimization of and Maximizing the Benefits from Pavement Management Data Collection
摘要：	A major component of a Pavement Management System is the regular monitoring of pavement condition to evaluate how a pavement section is performing over time and to determine when preventive and/or rehabilitative action should be taken to optimally preserve that section. While improved design procedures have significantly reduced the guesswork out of how to design a pavement section for the intended traffic and environmental conditions, construction and material variability and other uncertainties still contribute to significant variability in performance of similarly designed pavement sections and regular monitoring of pavement section is required for evaluating current condition and future performance. However, guidance is needed on: (1) optimum set of pavement condition data items for an effective pavement management system; (2) evolving technologies and possibility of new data items such as network level deflection measurements using Rolling Wheel Deflectometer (RWD); (3) optimum frequency of data collection; and (4) accuracy that should be achieved for reliable PMS analysis and decision-making. A fundamental part of this evaluation is the cost of data collection and the benefits. Of particular interest is the evaluation of incremental cost of additional pavement condition data items or increasing the frequency of data collection versus the incremental benefits. The project includes the following four tasks: 1) Recommend an optimum set of pavement condition data items, frequency of data collection and accuracy for an effective pavement management system. 2) Develop best practices and guidelines to integrate design, material and construction information within pavement management system. 3) Recommend procedures to guide the selection of optimum timing and treatment for pavement preservation and rehabilitation of a pavement section to achieve lowest life cycle cost. 4) Recommend procedures to comprehensively quantify the effectiveness of pavement preservation program at the network level.
