• 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.
