Research on Construction Technology of SMA-13 Asphalt Mixture with Rubber Asphalt

In order to study the key technologies of SMA-13 asphalt mixture construction, this paper summarizes a set of construction technology for mixing, transportation, paving and compaction in construction project. Relying on the real project, the road performance of the test section paved with this technology is tested. The research results show that the construction quality of rubber SMA-13 surface can be eff ectively improved by controlling the construction temperature and rolling scheme of each link, and strengthening the construction management and control, the compactness and water permeability coefficient can meet the design requirements, and there is no obvious damage at the early stage of the pavement.
