DOWNLOAD EBOOKThis report traces the development of a rating system proposed by the author and reviewed by a subcommittee of the Pavement Management Research Advisory Committee for use in evaluating the service condition of Virginia's Portland cement concrete pavements. The service condition is assessed in terms of distress roughness, i.e., that portion of a pavement's poor ride characteristics directly attributable to the occurrence of certain key distress types. The key distresses identified for jointed concrete pavements are permanent patching, lane/shoulder separation, transverse joint faulting, transverse joint seal damage, and scaling, map cracking, or crazing. For continuously reinforced pavements, spacing of transverse cracks, lane/shoulder separation, and scaling, map cracking, or crazing were identified. Field surveys of the occurrence of these distresses provided the necessary data for estimating distress roughness through the use of prediction equations that have been established from the standard statistical analysis of pavement section distress data and roughness measurements. The use of distress roughness to reflect a pavement's service condition provides a common basis for comparison of pavement sections. This, in turn, enables managers to set priorities for pavement rehabilitation. These rating procedures and a comprehensive system for managing Portland cement concrete pavements will be implemented in a subsequent project.

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKTo improve the planning mechanisms of highway maintenance and rehabilitation, many agencies have resorted to pavement management systems built as simple optimization models. These models are generally inadequate because they are too inflexible. The core of the proposed system is a general Markov decision process structure in which administrative divisions of the highway network (regions, districts) are explicitly taken into account. This basic structure is stated in an equivalent linear programming format which then allows for the addition to the model of various linear constraints. The other fundamental element of the system is a formal descriptive framework which is made up of a network language and a scenario language. This paper describes both languages, the general Markov decision process structure, and the current computer implementation of the system. Planned future developments are also outlined.

DOWNLOAD EBOOKThe study reported here addresses some of the earlier phases in the development of a pavement management system for the state of Virginia. Among the issues discussed are the development of an adequate data base and the implementation of a condition rating system. While the system envisioned is applicable to all Virginia pavements, such application on only the interstate system is discussed.
