PD-1 type bridge with polymer modified asphalt waterproof coating

[Product Description PD-1 type bridge with a polymer modified bitumen coating is a high quality heavy traffic asphalt-based material, adding rubber and resin materials modified by water-based waterproof coatings, based on polymer emulsion as the main membrane material, adding a variety of functional additives reaction from aqueous waterproof coating. The product is non-toxic, tasteless, no pollution, cold construction; the film has a dry, keeping rubber elasticity, low temperature flexibility; shear and strong, able to withstand long-term load and compression deck requirement to prevent structural damage caused by water leakage , delaying highway bridge life. Is the most ideal bridge waterproof material, can be used for roofing, underground, tunnel, cave and other water projects, seepage, corrosion, waterproof wall. PD-1 type bridge with a polymer modified bitumen waterproof coating not only a good performance, and road and bridge surface layer can absorb the stress and noise, as a stress-absorbing layer; because of their degree of elasticity and plastic deformation capability, to carry the load without being damaged. Bridge surface alleviate aging, anti-life. [Use] for bridge deck waterproofing, reinforced concrete bridge is prevented due to the corrosion caused by water seepage, improve the life of the beam. [Features] 1, has a broad temperature tolerance. When hot asphalt concrete construction work 140 ℃ ~ 180 ℃ not flowing, not brittle at low temperature dynamic loading -20 ℃ ~ -30 ℃; (2) the material cured film block, film toughness. Because the material is added chemical additives, the material can be a film in a short time, shorten construction time bridge deck waterproofing; 3, strong bond in the formula added penetrant and thickener to improve the penetration of paint ability and adhesion properties can be pavement and bridge deck into a cohesive whole. 4, the construction waterproof layer, the shear strength of the bridge deck and pavement reach 0.5 ~ 1.0Mpa, grassroots cracking 2mm, the film does not crack; 5, the construction Operability: high cold construction operations, mechanization, automation, materials non-toxic, do not pollute the environment. [PD-1 type polymer modified asphalt waterproof coating performance index requirements road and bridge projects] PD-1 type bridge with a polymer modified bitumen coating solids /% ≥ 45 low temperature flexibility / ℃ -25 Heat nature / ℃ 170 ℃ ± 2 ℃ no flow and slip coatings and concrete bond strength / Mpa≥ 0.4 impervious imperviousness /0.3Mpa,30min tensile strength / Mpa ≥ 0.50 elongation /% ≥ 800 dry, 25 ℃ Table dry ≤ 4h hard work ≤ 8h] [Construction Method Primary treatment: to use slag machine, shot blasting machine, milling machines and other equipment handle the bridge deck, the surface without floating pulp, smooth, clean, no clear water. Special parts of the deck discharge port, crash wall corner, etc. do enhance the process. Spray: PD-1 type bridge with polymer modified asphalt waterproof coating, spraying several times, coating thickness of the construction standards. Product protection: No hard work before traveling to prohibit pedestrians and vehicles. [Note] The above material construction temperature 5 ℃. Shall stir paint before use. Rain not construction, not more than five wind construction. Above 0 ℃ storage, transportation, avoid exposure, storage period of six months.
