Case Studies on Successful Utilization of Reclaimed Asphalt Pavement and Recycled Asphalt Shingles in Asphalt Pavements.

摘要

Over the past decade, the rapid cost escalation of raw materials used in highway construction has affected the ability of highway and road agencies to maintain their existing pavement system. A common strategy among many highway agencies to offset rising materials costs is to utilize more recycled materials in pavements, is also consistent with the desire to use more sustainable construction practices in the transportation infrastructure. This report describes the development of specifications and practices of a few state highway agencies that have successfully used RAP and RAS.
