The 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.
The report summarizes the developments in pavement management in the Virginia Department of Transportation through late 1986. Included are discussions of the pavement management process with examples of priority programming, long-range projection of maintenance-replacement needs, and the monitoring of pavement rating teams. The report shows that the Department has made great progress both in the development and implementation of the pavement management system. Several recommendations address areas in which the system can be "fine tuned" and made more useful to both top and middle management.
This report summarizes the activities undertaken to implement a pavement management system at 56 general aviation airports coming under the jurisdiction of the Virginia Department of Aviation (VDOAV). The system, which is called Micro-PAVER, is a proprietary program developed by the U.S. Army Corps of Engineers. It is reported to be used at many airports in the U.S. and abroad and by many local government agencies in the U.S. Implementation involved the training and the use of highway employees as airport inspectors, the development of an historical data base for each airport, cataloging the current condition of each runway pavement, and the development and inclusion of feasible maintenance policies and their estimated costs in a computer package. Finally, a series of condition and projected future condition reports as well as reports concerning the estimated rehabilitation costs were developed from the computer package for each airport. The project covered a period of approximately 18 months and utilized nearly 50 VDOT employees. Several recommendations to the VDOAV concerning the future of general aviation airport pavement management are included.
This 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.
The report summarizes the objectives and benefits of formal pavement management systems and outlines an approach believed by the author to be practical for Virginia. The management of Virginia interstate pavements and a proposed random-sampling plan for the primary and secondary systems are discussed. Five recommendations directed at initiating a pavement management system are offered. Perhaps the most important of these deals with the immediate establishment of a pilot management system for the interstate network. Projected costs of pavement management range from $100,000 to $200,000 for development of a system, depending upon the level of commitment, and approximately $90,000 in annual operating costs.
This report provides the background for the development of a pavement management system for the paved roads of Virginia's secondary highway system. Included are descriptions of a study to develop an acceptable surface-condition rating system for surface-treated (chip-sealed) pavements, a pilot application of the system, and an assessment of the resources required to implement the system. The system developed includes a means to capture data for ordinary or routine maintenance needs. A further part of this study involved a comparative analysis of the allocation of resurfacing monies on the basis of(1) a historical5-year program, (2) a 100 percent sampling approach, and (3) a 5 percent random sampling approach. Among the major recommendations are to proceed with full implementation of the system, including the provision of the needed resources; to use data from the system to determine the amount and allocation of the secondary resurfacing budget; and to capture data on ordinary maintenance needs for at least one cycle of pavement condition ratings.
