• Abstract:
  The California Department of Transportation (Caltrans) has been using scrap tire rubber (called crumb
  
  rubber modifier (CRM)) in asphalt pavements since the 1970s in chip seals and the 1980s in rubberized
  
  asphalt concrete (RAC). The performance of the projects has varied from poor to excellent, with
  
  relatively good overall performance. In recent years, however, improved specifications and practices
  
  have yielded more consistent performance.
  
  To evaluate the state of the technology of using scrap tire rubber in paving materials, a comprehensive
  
  review of the literature search was undertaken. Nearly 400 documents representing a cross-section of
  
  information and focused primarily on experience throughout the United States were reviewed. Findings
  
  were organized in the following topics areas, with some overlap: historical perspective; applications/field
  
  operations; materials selection and design; structural design; performance; recycling; cost; environmental
  
  issues; other uses; and specifications.
