What waterproof materials are used on roads and bridges?

3. Polymer modified asphalt waterproof coating: JC/T 408-2005 emulsion asphalt waterproof coating.

Waterproof coating for road and bridge Type I (SYC-FYT-I)/Type II (SYC-FYT-II):T/T 535-20 15 Waterborne Asphalt-based Waterproof Coating for Road and Bridge.

Type I (SYC-PB-I)/Type II (SYC-p B- I)/II) Waterproof Coatings for Road and Bridge: JC/T 975-2005 Waterproof Coatings for Road and Bridge.

Waterproof coatings for roads and bridges are based on petroleum asphalt and compounded with various polymer modified materials. After reasonable mixing, they can form crosslinked polymer coatings with excellent properties. It has the characteristics of good water resistance after polymer cross-linking polymerization, and good aging resistance and corrosion resistance of asphalt. After normal temperature construction and drying, high-quality waterproof elastic membrane can be formed, which can be attached to wet base surface, and has no pollution, no odor, no combustion and simple construction.

3. Polymer modified asphalt waterproof coating: JC/T 408-2005 emulsion asphalt waterproof coating.

Based on asphalt, a polymer-modified water emulsion or solvent-based waterproof coating is synthesized, which can be cured to form a film on wet base, with good adhesion, pressure penetration resistance, labor saving and construction cost reduction.

4.SBS modified asphalt waterproof coating

Using SBS*** thermoplastic elastomer as modifier, petroleum asphalt was modified, and rubber, synthetic resin, surfactant, emulsifier and other auxiliary materials were added, and it was refined by special equipment.

5.JC/T 2215-2014 "Spraying quick-setting rubber asphalt waterproof coating"

Waterproof coating for spraying quick-setting rubber asphalt adopts a special process, which is composed of superfine, suspended and microemulsion modified anionic emulsified asphalt and synthetic high molecular polymer, and then mixed with special curing agent to react, thus making excellent waterproof, seepage-proof, anticorrosion and protective coating.

6.JC/T 2428-2017 uncured rubber asphalt waterproof coating.

Rubber powder, asphalt and special additives are used as main raw materials. A waterproof material which keeps thick paste for a long time in the application state and has creep property. The coating can seal the cracks and pores of the base and adapt to the complex construction work surface; It will not solidify for a long time after contact with air, and special equipment is needed for construction.

The above waterproof materials are often used on roads and bridges. The construction method is simple, and mechanical spraying and shot blasting can be used. If you have any questions, you can pay attention to Song Xiao and show you more waterproof knowledge!
