DOWNLOAD EBOOKThis document is a comprehensive overview of the terminology, processes, products, and applications of crumb rubber modifier (CRM) technology. This technology includes any use of scrap tire rubber in asphalt paving materials. In general, CRM technology can be divided into two categories--the wet process and the dry process. When CRM is incorporated into an asphalt paving material, it will modify the properties of the binder (asphalt rubber) and/or act as a rubber aggregate (rubber modified hot mix asphalt). The five concepts for using CRM discussed in the report are McDonald, PlusRide, generic dry, chunk rubber asphalt concrete, and continuous blending asphalt rubber. An experimental work plan for monitoring performance and a stack emission testing program are also included.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKSection 1038 of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains provisions for each State to begin incorporating scrap tire rubber into their asphalt paving materials. A workshop was developed through the cooperation of highway agencies and the asphalt industry to discuss present procedures and practices for designing and constructing asphalt pavements which incorporate scrap tire rubber (crumb rubber modifier). These workshop notes were prepared from the proceedings of the 13 workshop sessions.

DOWNLOAD EBOOKDocuments the construction and performance of the research study which was initiated to address section 1038(d) of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA). The project selected to demonstrate the crumb rubber process was located on Platt Canyon (SH 75) from Bowles to C470 in the Denver metropolitan area. The project was a low volume roadway and quantities of crumb rubber introduced into the mix were minimal. This was to reduce risk in terms of premature failure and Colorado's limited experience with crumb rubber. Because of this limited experience, the "dry" process was selected. The project contained four different mix designs. A mix containing 1% [20 lb/ton (10 kg/Mg)] crumb rubber, a mix containing 1 lb/ton (0.5 kg/Mg), a mix containing 3 lb/ton (1.5 kg/Mg) and a mix which contained no rubber were placed on the project.
