The products are divided into hot-melt (R) or hot-melt (J) construction waterproofing membranes according to the construction method. According to the form of asphalt pavement layer, it is divided into I open type and II type. The upper surface material of the coil is fine sand (S). The hot-melt construction waterproofing membrane 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 waterproofing membrane is: fine sand (S).

Product Specification：

————

The product is based on long-fiber polyester felt as base material, and is made of plastic elastomer modified asphalt such as random polypropylene (APP) or polyolefin polymer (APAO, APO). Waterproof membrane. The material has high strength, large elongation and excellent heat resistance, flexibility and shear resistance. It can withstand long-term load movement of bridge deck, prevent structural damage caused by water seepage, steel corrosion, concrete carbonization, and greatly extend the use of bridge deck life.

PRODUCT

INTRODUCTION

FEATURES

PRODUCT

The product has excellent high temperature resistance and can withstand the rolling construction under high temperature.

①

High bonding strength and good adhesion to the base layer.

②

High strength and shear resistance can withstand the dynamic load of bridges.

③

It is excellent in impermeability and water impermeability and can resist the action of hydrodynamic pressure.

④

It is resistant to smashing, tearing, fatigue and aging resistance, and can resist the influence of high and low temperature dynamic loads on the bridge deck.

⑤

The coil is unfolded at the position of the elastic wire. The bottom layer and the base layer of the coil are baked with a flame spray gun, and the coil is laid. The edge is covered with a pressure roller to remove the air, so that the coil and the base layer are firmly bonded.
When the coil is constructed by hot melt method, the lap joint should overflow the hot melt modified bitumen.
Sealing is done at the lap and the end.
Notes:
● Construction is not allowed on rainy and snowy days and on windy days above Grade 5.
●The construction environment temperature of the coil should not be lower than -10 °C.

The base layer must be flat, rough, firm and fully dry, free of dust, oil and sharp corners.
Additional processing of detail nodes.
Brush the base treatment agent.
Then press the construction direction to determine the position of the coil.

The hot-melt coil material is constructed by hot melt method; the hot melt adhesive type coil material is constructed by hot melt adhesive method.
