The Evaluation of Hot In-place Recycling Technology in Asphalt Pavement's Pre-maintenance of Chongqing Expressway

摘要

This article mainly discussed the proper conditions for Hot In-place Recycling technology, construction process and its advantages as well as disadvantages in technical performance, and analyzed the actual project through experiments. The results showed that: after the application of Hot In-place Recycling technology, the pavement performance and asphalt mixture's indicators conformed with the specifications basically. Thus, this technology can improve the conditions of pavement and do both had the technical feasibility and the good economic efficiency and social efficiency for asphalt pavement's Pre-maintenance in expressway.
