This report focuses on the factors considered in the prioritization of pavement rehabilitation projects. The research team evaluated current practices for data collection and integration to gain an understanding of the potential needs for improvement in the decision-making process.
This document contains findings from a literature review and from a survey concerning New Zealand asset management practices. A strategy is proposed for the improvement of data collection and management, which in turn is expected to allow for further development of advanced bridge asset management.
This document describes the ways in which road deterioration (RD) models could be developed to assign various possibilities to a pavement's future (as opposed to offering one possibility), using a probabilistic approach. The report outlines the applications of a probabilistic approach at both the project and network levels.

This document provides an overview of a preventative approach to civil liability risk for road authorities. The report provides background information on claims against road agencies and recommends TAM practices for improved system performance and prevention of claims.
This study seeks to determine how state departments of transportation (DOTs) are using TAM and related techniques to address existing and anticipated future travel demand. Correspondingly, this study attempts to identify and document all cases in which state DOTs have incorporated travel demand measures within TAM and related analyses and decision-making processes.
To date, there has been a great deal of variability in how state highway agencies have established maintenance quality assurance (MQA) program components and how the results have been used to establish accountability, improve highway maintenance effectiveness, establish budget requirements, and allocate resources. Therefore, a domestic scan was organized through the U.S. Domestic Scan Program, which is managed under the auspices of the National Cooperative Highway Research Program (NCHRP). The domestic scan took place in October 2011 in Anaheim, California. The scan’s specific objectives included: 1. Explore the experiences of top-performing agencies, examining the degree to which their business plans and system-preservation strategic plans are linked to their MQA programs; 2. Identify successful strategies for linking customer expectations to agency performance measures; 3. Examine the variables that have most influenced the use of MQA results to improve agency accountability and/or support budgeting and resource allocation decisions; 4. Examine if, and how, different data measures, data-collection procedures, and data verification activities influence MQA program costs and the use of MQA results; 5. Examine the ways in which innovation has been incorporated into MQA programs; 6. Explore the ways highway maintenance and preservation information is presented to senior management, elected officials, and the public; 7. Explore the strategies (e.g., education and training programs) that have been used successfully to build buy in and accountability among field personnel; and 8. Identify technical and/or organizational challenges to overcome and strategies to improve the use of performance measures for highway maintenance and preservation activities. The findings and recommendations from the scan are summarized in this report.
