摘要：	Highway agencies have been evaluating crumb rubber modifier (CRM) technology applications at different levels of development since the 1970's. Ten CRM technologies were identified. The performance of asphalt pavements using CRM technology has been mixed. The amount of documented research on recycling CRM paving materials is limited. An analysis, using the results of seven studies, was conducted to compare the relative threats/risks to human health and the environment of conventional asphalt paving to CRM asphalt paving. The health/environmental comparison was influenced by numerous variables. The data contained no obvious trends to indicate a significant increase or decrease in emissions was attributed to the use of CRM. The highway construction industry has a long history of using recycled products for highway construction. The report summarizes some of the industries' experiences and, where sufficient information exists, it provides documentation regarding the economic savings, technical performance, threats to human health and the environment, and environmental benefits of using recycled materials in highway devices and appurtenances and highway projects.
