STUDY ON COLD ON-SITE RECYCLING CONSTRUCTION PROCESSES AND TECHNIQUES FOR OLD ASPHALT PAVEMENT

摘要

This paper takes DongHong road in LinYi ShanDong province as an illustration, to present the main principle and application prospects of cold on-site recycling technology for old asphalt pavement. Laboratory experiment and construction process of this technology are particularly introduced such as the old road milling, mixing the initial shaping, watering nausea materials, paving cement, the second mixing, shaping, rolling, joint treatment, curing, etc. Based on trial research and construction practices, it provides cold-place recycling construction technology for the old asphalt pavement, which is especially suitable for northern part of china. The results will play an active action on drawing up the construction standards and on the extensive application of cold on-site recycling technology for the old asphalt pavement for the future and also become the necessary way to reduce costs, save resources and develop circling economy.
