Flexible Pavement Rehabilitation And Maintenance

Papers from a December 1997 symposium detail innovative and effective strategies for rehabilitation and maintenance of existing highways. Primary topics addressed include pavement evaluation for rehabilitation and management, cold in-place recycling techniques for pavement rehabilitation, effectiven

"This synthesis will be of special interest to maintenance engineers and others seeking information on strategies for parvement maintenance. Detailed information is presented on the selection of alternative treatments within the context of a pavement management system."--Avant-propos.

This book was written by academic's and practitioners who have lead the implementation of highway management processes and tools at several major corporations. The contents of this book have been presented in an interesting and enjoyable way, enhanced by real pictures of highway projects and pavement maintenance. This book contains five chapters, the first chapter entitled MAINTENANCE MANAGEMENT: It was to clarify the concept and importance of maintenance and management professionally and smoothly, While the title of the second chapter is the HIGHWAY PROJECTS, and provided a detailed explanation of the management and implementation of highways, while reviewing the types and importance in the construction sector. The third chapter, entitled PAVEMENT DETERIORATION: The researchers reviewed the types of DETERIORATION in the riged and asphalt pavement, and explained the methods of treatment and maintenance necessary for each type. While the fourth chapter was entitled HIGHY WAY MAINTENANCE OPERATIONS: It reviewed the methods of maintenance and importance in highway project, the fifth chapter entitled: PAVEMENT MAINTENANCE MANAGEMENT SYSTEM: This chapter reviewed the most important global strategies in the management of pavement maintenance.

This synthesis will be of interest to highway agency executive management including administrative, budget, and finance personnel; pavement design, construction, and maintenance engineers; and maintenance operations personnel, including supervisors and maintenance crew leaders. This synthesis describes the state of the practice with respect to setting a coherent strategy of cost-effective preventive maintenance for extending pavement life. This report of the Transportation Research Board describes the practices of state, local, and provincial transportation agencies that are attempting to minimize the life-cycle costs of pavements and are identifying, during the design of the pavement rehabilitation, reconstruction, or construction projects, the future preventive maintenance treatments and the timing and funding for those treatments. It includes a review of domestic literature and a survey of current practices in North America. The appendices include a primer on pavement design and construction, the benefits of preventive maintenance of pavements, a summary of the questionnaire data collected, a simulation of pavement management strategies, and an example process to demonstrate the cost- effectiveness of preventive maintenance.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
