Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 523: Optimal Timing of Pavement Preventive Maintenance Treatment Applications describes a methodology for determining the optimal timing for the application of preventive maintenance treatments to flexible and rigid pavements. NCHRP Report 523 also presents the methodology in the form of a macro-driven Microsoft Excel Visual Basic Application--designated OPTime"--Publisher's description.

Book Description
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.

Book Description
TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways 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.

Book Description
The purpose of this handbook is to provide background information about the importance of pavement preservation and preventive maintenance, as well as present maintenance techniques for a variety of distresses and conditions. The major focus of this handbook is on preventive maintenance activities, which are performed while the roadway is still in good condition with only minimal distress, before the pavement falls into a condition where structural overlays, major milling or reclaiming, or replacement is necessary. The most common flexible pavement distresses are cracking, roughness, weathering, raveling, rutting and bleeding. If the distresses identified in a pavement are related to structural deficiencies, the pavement section is most likely not a candidate for preventive maintenance treatment, and should be scheduled for rehabilitation or reconstruction. Maintenance treatments covered in this handbook include: Crack repair w/sealing, including clean and seal, saw and seal, and rout and seal; crack filling, full depth crack repair, fog seal, seal coat, double chip seal, slurry seal, microsurfacing, thin hot mix overlays, and potholes and pavement patching. Tables are outlined giving the most common flexible pavement distresses, along with the best practices for rehabilitation for each. Also given are recommended applications for crack sealers and fillers, surface treatments, and pothole patching. Specifications, technical memoranda and special provisions are included for all treatment methods recommended in the handbook.

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.

Book Description
This book provides an overview of asphalt pavement maintenance, highlighting the key asphalt pavement maintenance technologies in China. It analyzes the trend toward preventive maintenance technologies and proposes technical guidelines and implementation rules for preventive maintenance. As such it is a valuable reference resource for technicians in related industries, both in China and abroad, as well as professionals involved in road infrastructure maintenance projects in countries participating in the Belt and Road Initiative.
