The main goal of this research was to help users determine the proper timing of preventive maintenance by identifying how environmental aging affects asphalt material properties (binder and/or mixture) in the pavement and how the application of pavement preservation treatments impact the aging process. Two main test sections were studied: (1) a designed experiment on the Low Volume Road portion of MnROAD to look at aging through the application of treatments on an annual basis over a five-year period; and (2) a 10-year-old pavement on TH 56 in southern Minnesota, also a designed experiment, with seals applied on an annual basis over a four-year period. Mix testing on TH 56 cores indicated that subsections with chip seals applied more than two years after construction had essentially the same fracture energy properties as the unsealed control subsection - implying that the initial treatment from a preservation standpoint should occur within the first two years of the pavement's life to mitigate damage from environmental aging. The MnROAD sections did not show the same response. Based on the testing conducted during the study and the associated findings, it appears that rheological tests can be conducted on the asphalt binder recovered from a pavement core to assess the effects of oxidative aging. When possible, it appears prudent to use a mixture fracture energy test, such as the DC(T), in conjunction with asphalt binder rheological testing to quantify the effects of aging within a pavement and suggest appropriate timing for the application of preservation treatments.

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.

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.

Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements, from soil preparation to structural design and construction. This new edition includes updates in all chapters and two new chapters on emerging topics that are becoming universally important: engineering of sustainable pavements and environmental mitigation in transportation projects. It also contains new examples and new figures with more informative schematics as well as helpful photographs. The text describes the significance of standards and examines traffic, drainage, concrete mixes, asphalt binders, distress and performance in concrete and asphalt pavements, and pavement maintenance and rehabilitation. It also contains a chapter on airport pavements and discusses nondestructive tests for pavement engineering using nuclear, deflection-based, electromagnetic, and seismic equipment. The authors explore key concepts and techniques for economic analysis and computing life-cycle cost, instrumentation for acquiring test data, and specialty applications of asphalt and concrete. The Second Edition includes more relevant issues and recently developed techniques and guidelines for practical problems, such as selection of pavement type, effect of vehicle tires, and use of smart sensors in rollers and software for drainage analysis. This book presents in-depth, state-of-the-art knowledge in a range of relevant topics in pavement engineering, with numerous examples and figures and comprehensive references to online resources for literature and software. It provides a good understanding of construction practices essential for new engineers and materials processing and construction needed for solving numerous problems.
