Embodiment Construction
[0032] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.
[0033] A kind of epoxy asphalt steel bridge deck pavement method, such as Figure 1-2 , including the following steps:
[0034] 1) Sandblasting and derusting of the bridge deck: fully automatic dust-free sandblasting equipment is used for operation, and the corners of the steel bridge deck 1 are derusted by manual grinding process; Reach the requirements of Sa2.5 level; the roughness requirements reach 50-100μm.
[0035] 2) Epoxy bonding layer 2 laying: Before the bonding layer is spread, use a soft broom to sweep away the dust and debris on the steel bridge deck 1; if there is oil, clean it with...

Abstract
The invention discloses an epoxy asphalt steel bridge deck pavement method. The epoxy asphalt steel bridge deck pavement method comprises the following steps: 1) conducting sand blasting and rust removal on a bridge deck; 2) laying an epoxy bonding layer: laying an epoxy asphalt binder for 2 mm at first, and then laying a layer of macadam with the diameter of 3-5 mm, and then spraying the epoxy asphalt binder on the macadam, wherein the spraying amount is 0.45 + / - 0.03 kg / m < 2 >; 3), paving epoxy resin asphalt concrete: compacting after paving; 4), paving an asphalt mastic macadam mixture. Amacadam layer is formed in the epoxy bonding layer laying process, the macadam layer is different in macadam size, the surface of the formed macadam layer is uneven, therefore, the contact area between the epoxy bonding layer and the epoxy resin asphalt concrete is increased, and the bonding force between the two is enhanced; the epoxy resin asphalt concrete is hard to slide; the uneven surface has the effect of preventing the epoxy resin asphalt concrete from sliding, and the bonding force between the asphalt mastic macadam mixture and the epoxy resin asphalt concrete is high due to the goodviscosity of the asphalt mastic macadam mixture.
Description
technical field [0001] The invention relates to steel bridge deck construction, in particular to an epoxy asphalt steel bridge deck paving method. Background technique [0002] Steel box girder steel deck pavement materials have always been a hot spot and difficulty in the world. The steel bridge deck pavement material is directly laid on the steel plate. Under the influence of driving load, wind load, temperature change and earthquake and other factors, its force and deformation are far more complicated than that of highway pavement or airport pavement, so its strength and deformation are stable. There are higher requirements for performance, fatigue durability, etc. [0003] The steel bridge deforms a lot under the action of temperature and load, and the steel box girder has good temperature conductivity and is easily affected by changes in external temperature. In the high temperature season in summer, the measured temperature of the steel plate on the top surface of th...
