Book Description
This synthesis on the use of recycled rubber tires in highways will be of interest to administrators and policy-makers; pavement, materials, geotechnical, environmental, and traffic operations engineers; and research engineers involved with highway design and construction issues. Information is provided on the uses of rubber tires in asphalt paving materials as well as other uses, such as on fills and embankments, for erosion control and on railroad grade crossings. Specifically, information is included which identifies the agencies using or implementing applications for recycled rubber tires and defines the design parameters, technical and construction limitations, performance, costs, benefits, environmental limitations, specifications, and availability. This synthesis of information defines the use of recycled rubber tires in highways and is based on a review of nearly 500 references and on information recorded from state highway agency responses to a 1991 survey of practice. Updates are included for as much of the state practice information possible through 1993. The use of scrap tires for highway applications is dynamic with regard to policy and technical issues. Therefore, the reader should keep in mind that the information presented reflects the best available data at a particular time. The synthesis also identifies current research in the topic area, critical research needs, and legislative issues that affect application and use of recycled rubber tires.

Book Description
Chip seal is one of the most popularly adopted pavement preservation strategies. A chip seal treatment is constructed by adding hot asphalt or emulsion on the surface of an existing pavement, spraying aggregates on the top, followed by roller compaction. Extensive research has led to the formulation of various chip seal analysis and design methodologies. These methods are mostly empirical in nature and depend on numerous assumptions related to chip seal microstructure and their expected behavior after compaction in field. Hence, there is a need for in-depth analysis of chip seals to develop performance-based design methods addressing the primary distresses as well as the microstructural parameters such as percent embedment and aggregate orientation. The objective of this research study was to evaluate chip seals through image-based microstructural parameters and performance tests. The results of a comprehensive experimental program lead to development of a holistic approach to chip seal design, encompassing various aspects of chip seal performance through aggregate-binder microstructural perspective. New image processing techniques were developed to understand the percent embedment and aggregate orientation behavior. Additionally, finite element analyses were performed using actual chip seal images to evaluate mechanistic characteristics (e.g., magnitudes of strains at the aggregate/binder interface) responsible for chip seal performance. Further, extensive performance tests were run in laboratory to evaluate the effect of design parameters (e.g. percent embedment, aggregate orientation) on chip seal performance distresses (aggregate loss and bleeding). The results were combined and analyzed to yield new insights into effect of microstructural parameters on chip seal performance. Furthermore, a performance-based design procedure was developed for design of chip seals. This procedure integrates the chip seal microstructural behavior and its performance.
