摘要：	The FHWA, asphalt paving industry, academia, technology transfer centers, and State highway agencies developed a 2-day workshop on crumb rubber modifier (CRM) technology. Experts in asphalt paving and CRM technology prepared the document as a part of the workshop and used it to compose the presentation materials. The workshops were held in February and March of 1993 at seven locations across the country. Over 1,400 engineers, contractors, and interested individuals attended the workshops. The document is a comprehensive overview of the design procedures and construction practices for CRM technology. The CRM technology encompasses any use of scrap tire rubber in asphalt paving materials. The workshop notes begin with an overview of national and State legislation. The production of CRM material is described in detail and the history/description of individual technologies are discussed. The majority of the document focuses on the specific issues of cost factors, specification guidelines, pavement applications, binder design, mixture design, and construction practices.
