Example Embodiment
[0045] Example 1
[0046] Such as figure 1 As shown, the steel bridge deck pavement structure of this embodiment is provided with an anticorrosive layer 2, a lower bonding layer 3, a lower gravel layer 4, a structural layer 5, and an upper bonding layer on the steel bridge deck 1 from bottom to top. Layer 6, the upper gravel layer 7 and the wear layer 8; the anticorrosive layer 2 and the structural layer 5 are bonded by the lower bonding layer 3, and the structural layer 5 and the abrasion layer 8 are bonded by the upper bonding layer 6; the lower layer The crushed stone layer 4 is embedded between the lower bonding layer 3 and the structural layer 5, and the upper crushed stone layer 7 is embedded between the upper bonding layer 6 and the wear layer 8.
[0047] The anti-corrosion layer 2 is coated with epoxy zinc-rich paint, which is mainly composed of epoxy resin, polyamide resin, aluminum paste and additives; the thickness of the anti-corrosion layer 2 is 82 μm.
[0048] The low...
