Product description:
Product is the atactic polypropylene (APP) or a polyolefin-based polymer (APAO, APO and more) modified asphalt waterproof sheet ,using polyester mat reinforcement which is surfaced by isolated materials on the two sides
The material has high strength, large elongation and excellent heat resistance, flexibility, shear resistance, can withstand the deck load movement for a long time, and can prevent the structure damage, steel bar corrosion, concrete carbonation caused by the water seepage, greatly extend the service lifespan of bridge deck
Product features:
1. Superior heat resistance, low temperature flexibility, it can resist the effect of high, low temperature changes and dynamic load on the deck
2. Excellent shear resistance, it can withstand the structure deformation of heavy load and shearing of horizontal load
3. High tensile strength, elongation, and strong ability to adapt to the grass-roots shrinkage deformation and crack
4. It can form high strength waterproof layer,and the ability to resist pressure water is strong
5. Break resistance, tear resistance, fatigue resistance, corrosion resistance, mold resistance, weather resistance are good
6. Hot- applied construction method, construction is convenient and hot joint is reliable and durable
Application fields:
It is widely used in various types of bridge waterproofing, is applicable to pavement of asphalt concrete through paving style and pouring-style, and also used in parking, airport runways and other water engineering
Construction points
Hot melt construction method
1 .Basic level must be smooth, rough, solid and fully dry, free of dust, oil stain and sharp angle
2 .Do additional treatment on detail nodes
3 .Brush substrate treating agent
4 .Then according to the construction direction, do snap-line and determine the coil position
5. Spread sheet in the position of snap-line, using the spray gun to bake bottom and substrate of the sheet, do paving, while paving sheet, roll and compact sheet, exclude air to make the material and substrate be firmly bonded
6 .When paving sheet with hot-applied method, width of modified asphalt in lapping position that overflow is around 2mm, uniform and straight appropriately
7. Do sealed treatment in the lap and closeout position
