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.

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 study evaluated 6 specific preventive treatments. Four treatments are for asphalt concrete surfaced (flexible) pavements: chip seals; crack sealing; slurry seals; and thin overlays. Two treatments are for portland cement concrete surfaced pavements: joint and crack sealing; and undersealing. Performance of the pavement sections with the treatments was compared with the performance of a similar pavement section without the treatment. Performance is measured in terms of pavement distress, roughness profile, surface friction, and structural capacity. All of the flexible pavement test sections and most of the rigid pavement test sections have been constructed. Performance data are being collected. This report discusses the experimental design, project selection, construction, data collection, analysis, and future activities of the pavement maintenance effectiveness project.

Book Description
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.

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.
