Cold Recycling Technology Application of Old Asphalt Pavement in Rural Road Alteration Engineering

摘要

Cold recycling technology of old asphalt pavement is a relatively new technology which has important application in the road surface treatment.Combining with the application of the cold recycling technology in rural old asphalt pavement,this paper analyzes and elaborates its construction technology and experience approach.The existing old asphalt pavement material is used in accordance with the new design requirements to form a special pavement structure surface.On rolling forming sections,the test is conducted for compaction,smoothness,bending and sinking and drill-core sampling for compressive strength.The results show that this process meets the general requirements of pavement base,and the quality is good with the advantages of saving costs and reducing waste damaging the environment.
