Further, a kind of anti-freezing ice double deck above-mentioned conserves structure, and the anti-freezing ice upper layer is that sustained release is anti-
Solidifying ice SMA-13 mixtures, 5% particulate slow-release type anti-freezing ice material is mixed by China and foreign countries.
Further, a kind of anti-freezing ice double deck above-mentioned conserves structure, and the adhesion coating is high adhered modification emulsification drip
Green adhesion coating.
Further, a kind of anti-freezing ice double deck above-mentioned conserves structure, and the cutting optimal of mating formation is 4~8cm thick
The SMA-13 mixing bed of materials of degree.
Further, a kind of anti-freezing ice double deck above-mentioned conserves structure, and the water-proof tack coat is water-base epoxy
Asphalt waterproofing adhesive layer, water-proof binding layer material use water-base epoxy pitch, belong to environmentally friendly, colod-application, rapid curing water material,
Have the characteristics that shear behavior and permeability are superior.
By above-mentioned technical proposal, the anti-freezing ice double deck maintenance structure of the utility model at least has following advantages：
The anti-freezing ice double deck of the utility model conserves structure, can effectively improve the anti-freezing ice ability of bridge deck structure,
Ensure traffic safety；Anti-freezing ice material selection particulate slow-release type anti-freezing ice material, the material are mainly made of sodium chloride, are used
Macromolecule film-coating technique is modified, make active ingredient (sodium chloride) can slow release, hardness is big, can effectively reduce road surface
Freezing point can effectively prevent bridge floor from being formed and freeze, Applicable temperature face is wider to -14 DEG C；Under the conditions of moderate or heavy snow, anti-freezing ice is double
Layer deck paving can reduce the cohesive force between ice sheet and road surface, to be conducive to clean；In addition, passing through the anti-freezing of bridge floor active
Ice, compared with traditional passive clearing ice technology, can it is cost-effective and on bridge structure and periphery green plants without influence.
