Book Description
This synthesis will be of interest to highway administrators; pavement management system (PMS), maintenance, and computer engineers; and technologists involved with data collection and computer programming for the purposes of a PMS. This synthesis describes the state of the practice with respect to pavement management methodologies to select projects and recommend preservation treatments. This report of the Transportation Research Board also describes the predominant pavement management methodologies being used by U.S. state and Canadian provincial transportation agencies; provides a general description of each methodology; and summarizes the requirements, benefits, hindrances, and constraints associated with each. It includes a review of domestic literature and a survey of current practices in North America. In addition, case studies are included to illustrate the use of these methodologies within transportation agencies. Operational and soon-to-be implemented technologies are also discussed, and an extensive bibliography is provided for further reference.

Book Description
The priority assessment analysis method, as a part of a Pavement Management System, is the most appropriate one for short and medium term road network improvement planning, while the network optimization methods serve for the long term policy defining. Their optimization criteria are expressed in different terms. Both systems may represent two stages of a unique planning process - a conceptual and a detailed one. To use these systems for such purposes their results must be compatible. Optimal strategies from both investors and users points of view, obtained by the network optimisation method, were introduced into HDM - III, avoiding the Expenditure budgeting Model (EBM). All the results were translated into the same units or criteria. The predicted effects, especialy those that consider the use of available resources, were better than those obtained by the standard procedure. The relations between the users and the agency costs for different traffic categories and budgeting levels were observed. Such an approach meets the needs of networks which are far from an optimal steady state. For the covering abstract of this conference see IRRD number 872978. (A.

Book Description
Optimal use of pavement maintenance and rehabilitation dollars is essential in a constrained budget environment such as now. A network-level optimization tool, which could generate the best maintenance and rehabilitation strategies for the entire pavement network, has become necessary for many highway agencies. This thesis presents the development and implementation of a network-level optimization tool within a pavement management information system for the Ohio Department of Transportation (ODOT). Future pavement condition is predicted based on historical pavement data using a Markov transition probability model. Such transition probabilities are updated automatically when new condition data become available each year. The network-level optimization tool integrates a linear programming model and the Markov transition probability model. This optimization tool is capable of (1) calculating the minimum budget required to achieve a desired level of pavement network condition, (2) maximizing the improvements of pavement network condition with a given amount of budget, and (3) determining the corresponding optimal treatment policy and budget allocations. It can be used by highway agencies as a decision support tool for network-level pavement management.

Book Description
The purpose of this study was to prepare guidelines that can be used by state level pavement management engineers to help them perform their work more effectively. One of the key activities covered is how to deal with evolving technologies that affect data collection, storage, and presentation process.
