Modified asphalt waterproof membrane for road bridge and high-speed railway
Scope of application
Self-adhesive, SBS and APP I coils are mainly used for paving asphalt concrete. APP II coils are mainly used for pavement of cast asphalt concrete mixture.
Waterproofing of railway bridge decks, highway bridge decks, and tunnels. Especially suitable for projects with high requirements on the extension of the waterproof layer and low temperature flexibility
product type
●Products are divided into: (Z) self-adhesive construction, (R) hot-melt or (J) hot-melt adhesive construction waterproof coiled material.
●The hot-melt or hot-melt adhesive construction waterproof membrane is divided into different types of modified materials: elastomer (SBS) and plastic (APP) modified asphalt waterproof membrane.
Self-adhesive construction waterproof membrane is a self-adhesive rubber-modified asphalt waterproof membrane mainly based on SBS and added with other polymers.
●APP modified asphalt waterproof coiled material is divided into type I and type II according to the different types of asphalt pavement.
The upper surface material of the coil is fine sand (S).
Hot-melt construction waterproof coiled material is divided into: polyethylene film (PE) and fine sand (S) according to the surface material.
The material of the lower surface of the hot-melt adhesive construction waterproof coiled material is fine sand (S).
Thickness, 25mm 3.5mm 4.0mm 4.5mm
Product Features
●All the features of APP / SBS.
●It has excellent heat resistance, excellent high temperature shear resistance and dimensional stability.
●Good anti-aging performance.
●Strong anti-breaking ability, able to withstand the bare crushing of equipment and puncture of pellets during construction.
●High tensile strength, high elongation, and high viscosity strength with coagulants.
●No foaming and layering, good impermeability, can withstand repeated driving and water pressure.
●Good acid, alkali and salt resistance, free from freezing and thawing cycles.
Engineering performance of special waterproof membrane for Daqiao high-speed railway
The modified asphalt waterproof coiled material used for roads and bridges can withstand the rolling construction of hot asphalt concrete at high temperature. It has a strong bond strength with hot asphalt concrete and can transfer the heavy traffic horizontal load.
The modified asphalt waterproof membrane used for roads and bridges has large physical properties, and has the function of strengthening the backing of asphalt concrete, which can effectively prevent the generation and development of asphalt concrete cracks, improve the service life of asphalt concrete pavement and the comfort of vehicle operation.
Waterproof performance of modified asphalt waterproof coiled material for road and bridge: the cracks and empty water of the asphalt concrete surface layer on the road and bridge will produce a huge "pump" pressure water effect under the action of driving load, which will protect the reinforced concrete structure to the steel bars.
The strength, elongation, high and low temperature performance of modified asphalt waterproof membrane for roads and bridges are superior to ordinary self-adhesive, SBS and APP waterproof membranes, and ordinary self-adhesive, SBS, APP membranes must not be used on roads .
