YWR-453 Polymer Modified Bitumen Waterproof Membrane for High-speed Rail

The product is made of long-fiber polyester felt as the base material, high-polymer modified asphalt as the coating material, and double-sided coated with fine sand insulation material. The material has high strength, large elongation and excellent heat resistance, flexibility and shear resistance. It can withstand long-term load movement of roads and bridges, prevent structural damage caused by water seepage, steel corrosion, concrete carbonization, and greatly extend the service life of roads and bridges.

Scope of Application

It is suitable for anti-corrosion, anti-seepage and waterproof of high-speed railway, highway, culvert and concrete bridge deck engineering.

Product Features

●Super heat resistance, low temperature flexibility, and can resist the influence of high and low temperature dynamic loads on roads and bridges.
●Excellent shear resistance, structural deformation capable of withstanding heavy loads and shearing of horizontal loads.
●The tensile strength is high, the elongation is large, and the adaptability to the shrinkage deformation and cracking of the base layer is strong.
● It can form a high-strength waterproof layer and is resistant to pressure water.
●It is resistant to smashing, tearing, fatigue, corrosion, mold and weather resistance.

Construction Method

Construction by hot melt method.
Base layer requirements: Before laying the coil, the surface of the base layer should be removed from the slurry and dust; the surface of the base should be dry, free of oil and solid.
Processing the base layer: Before the coil material is applied, the high-polymer modified asphalt base layer treatment agent should be applied to the base layer, and the base layer treatment agent should be evenly coated, not exposed, and not stacked; when the base layer treatment agent is dry and not sticky, For the paving of the coil, it is recommended to use not less than 0.4kg per square meter.
Construction steps：
1. Coil positioning and elastic wire.
2. The coil is pre-laid at the position of the elastic line, releasing the stress, rolling the coil from the two ends to the middle, uniformly baking the bottom layer and the base layer of the coil with a flame spray gun, and winding the coil from the middle to the both ends of the coil. Paving, compacting while laying, excluding air, so that the coil and the base layer are firmly bonded.
3. There should be natural overflow of molten asphalt at the lap joint to ensure that the lap joint is firmly attached. The longitudinal length of the web shall not be less than 100mm.
4. The waterproof membrane should be laid on the bridge deck to the retaining wall and the root of the vertical wall.
5. The lap and the end of the place to do a good job of sealing.
Notes：
It is not allowed to be constructed on rainy, snowy days and five windy days;
The construction environment temperature of the coiled material should not be lower than -10 °C.
