Abstract

The invention discloses a cast asphalt concrete paving and construction process. The process comprises the following steps: 1) a preparation section, wherein raw material mix proportion design, resource inspection, transport vehicle preheating, bridge deck measurement and bridge deck cleaning are conducted; 2) a production section, wherein mixed material production and quality inspection are carried out; 3) a transportation section; 4) a paving section, including preparation before paving, mixture paving, penetration test and treatment after paving; and 5) a detection section, wherein seam setting, boundary treatment checking and accepting are conducted. According to the invention, cast asphalt concrete has the advantages of being good in impermeability, high in construction speed, high in deformation adaptability, convenient and easy to construct, weak in dependence on environmental climate, small in influence of the environmental climate, even capable of being constructed in winter, short in paving time and capable of reducing interference to the surrounding environment.

Description

technical field [0001] The invention relates to the technical field of steel box girder bridge deck construction, in particular to a construction technique for pouring asphalt concrete pavement. Background technique [0002] Modern clean production requires the floor of the workshop to be clean and wear-resistant, and the dust content in the indoor air to be as low as possible. This is not only a requirement for improving working conditions, but also a guarantee for product quality. As an industrial floor coating, epoxy resin coating has good wear resistance, dust resistance, chemical resistance, and mechanical impact resistance. Therefore, most of the existing road and bridge decks are directly paved with epoxy resin. [0003] The following problems existed in the paving construction of epoxy resin coatings in the past: 1. The cost of raw materials is high, the construction period is long, and time-consuming and laborious; 2. The paving is highly dependent on the climate an...
