Research and Application Prospect on Cold Recycling Technology of Asphalt Pavement

摘要

Cold recycling technology is applied to road rehabilitation in the recent years, and it has the advantages of mixture without heating, high RAP availability, low cost, quick speed of construction etc. Cold in-place recycling technology in this paper has been summarized including applied scope, cold recycling layer type, additives and new aggregates. We gives a detailed comparison and analysis to cold recycled mixture design method, and points out important design indexes. Combined with practical engineer of the technology in China, it analyzes application prospect and development trend on cold recycling technology.
