Publication Details
Primary Topic: Pavement Recycling Description: Highway agencies have been evaluating crumb rubber modifier (CRM) in hot mix asphalt (HMA) since the 1970's. Three agencies, Arizona, California, and Florida, used CRM in HMA at levels that would approach or exceed the mandate in Section 1038 of the Intermodal Surface Transportation Efficiency Act of 1991. This report documents the use of CRM in HMA in these three States. In particular, it addresses issues including thickness design, materials and mix design, construction procedure, including quality control, and pavement performance. The report also addresses the following questions: (1) What processes are used? (2) Why are they used? (3) How are the products performing?.
