摘要

Scrap tires are a serious disposal problem and continue to accumulate at increasing rates. If not managed properly the scrap tires will present increasing environmental problems. Utilization of scrap tires should minimize environmental impact and maximize conservation of natural resources. As a result, both government agencies and environmental groups have strongly supported scrap tire management programs. Each state has its own scrap tire laws and regulations regarding scrap tire storages, collection, processing, and use. The regulatory practices include landfill bans and scrap tire fees. Scrap tires can be shredded into raw materials for use in hundreds of crumb rubber products. The crumb rubber market has been one of the fastest growing scrap tire markets over the last six years. One of the most interesting and potentially large-volume uses for crumb rubber is in rubberized asphalt pavement. Although the rubberized asphalt pavement indicate many advantages, many state highway departments have not been convinced of the merits of using rubberized asphalt in a major capacity. Deterrents for the use of crumb rubberized asphalt include high initial cost and occasional poor performance under certain conditions, when compared to conventional asphalt concrete. However, when one compares rubberized asphalt to conventional paving on a life cycle basic, the life cycle costs are less disparate.
