A literature review on cold recycling technology of asphalt pavement

Due to the advantages of less raw materials and fossil fuel consumption, lower carbon footprint, and the capability of pavement performance improvement, the recycling technology of asphalt is developed and applied for road rehabilitation and construction in the western countries over the past two decades. However, some technical problems still need to be concerned about, for instance, the techniques in recycling process and the optimization of mix design. In order to promote the application of cold mixing technology in practice widely, and better follow up the research progress of cold recycling technology, this paper reviewed and discussed the classification of cold recycling, the scope of application, raw materials, mix design procedure and construction technology, test method, pavement performance.
