Evaluation of the Use of Scrap Tires in Transportation Related Applications in the State of Washington. Report to the Legislature as Required by SHB 2308

摘要

House Bill 2308 (2002) directed the Washington State Department of Transportation to evaluate scrap tire use in civil engineering and road building applications. Specifically, HB 2308 directed evaluation of scrap tires for lightweight fills and rubber modified hot mix asphalt (HMA) pavement. In carrying out this study WSDOT conducted extensive literature searches on both lightweight fills and pavements, surveyed all 52 AASHTO members on their use of scrap tires, reviewed the FHWA protocol for constructing lightweight fills, and reviewed the history of lightweight fill and crumb rubber projects in Washington State.
