Construction Technology of Warm Mix Retardant Asphalt Mixture

Abstract:

As a new material, the warm mix asphalt retardant asphalt mixture has its particularity in material design, construction proportion, mixture preparation and on-site paving. This paper summarized the construction process and site construction quality inspection requirement of the warm mix asphalt retardant asphalt mixture through tracking research on-site based on the real engineering. It was shown that the road environment quality of using warm mix retardant asphalt was significantly better than normal hot mix asphalt, asphalt smoke, benzene soluble and Benzopyrene decreased 91.47%, 97.05% and 80.11% respectively. Warm mix asphalt retardant asphalt mixture had a low mixing and compaction temperature. When used in the tunnel pavement, it could not only greatly reduce harmful gas emissions in the process of construction, improve construction environment in tunnel, improve the air transparency in tunnel, be convenient for construction quality management, but also can improve the fire resilience of the tunnel pavement after be put into operation. It had broad application prospect in the tunnel pavement.
