Book Description
The continued preservation of ADOT's pavements becomes an ever- increasing issue as non-renewable resources such as mineral aggregate become more and more difficult to obtain. Historically, ADOT's design philosophies have resulted in strategies that consist primarily of mill and fill and overlay. These pavement strategies are designed for approximately a ten year life, at which time, another similar treatment would be performed. Proper design philosophies evaluate life cycle costs to select the best available design option. However, the life cycle cost consists of both the construction cost and the user cost incurred by the public through delay, etc. While construction costs are easily defined, user costs are very difficult to quantify and often times may actually exceed the actual cost of the facility being constructed. Since the user costs are not directly borne by the agency, it becomes somewhat of a philosophical discussion as to what user costs should be considered. In recent times, mineral aggregate sources have become increasingly more difficult to obtain in Arizona. However, our current design philosophies and economics requires needing new materials approximately every ten years. There is a need to consider reconstruction of significant roadways so that they can obtain design lives, perhaps as many as thirty to forty years before rehabilitation or reconstruction.

Cost-effective Preventive Pavement Maintenance
Author: Donald N. Geoffroy
Publisher:
ISBN:
Category : Business & Economics
Languages : en
Pages : 116
Book Description
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.

Preservation Approaches for High-traffic-volume Roadways
Author: David G. Peshkin
Publisher: Transportation Research Board
ISBN: 0309128919
Category : Technology & Engineering
Languages : en
Pages : 179
Book Description
TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-1: Preservation Approaches for High-Traffic-Volume Roadways documents the state of the practice of preservation treatment on asphalt and concrete pavements on high- and low-volume roadways. The report also includes general guidelines on the application of preservation treatments on high-volume roadways. The same project that produced SHRP 2 Report S2-R26-RR-1 also produced SHRP 2 Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways, which explores the state of the practice for preservation treatments on high- and low-volume asphalt and concrete roadways. The report also includes suggested guidelines on the application of preservation treatments on high-volume roadways.

Pavement Management Methodologies to Select Projects and Recommend Preservation Treatments
Author: Kathryn A. Zimmerman
Publisher: Transportation Research Board
ISBN: 9780309058667
Category : Technology & Engineering
Languages : en
Pages : 108
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.
