Fiber reinforced deck Waterproof coating Construction guidance
1、 Product Introduction
Fiber reinforced deck waterproofing coating Non toxic, tasteless, no environmental pollution, cold construction; The main advantage is modification asphalt The rubber in the middle forms a continuous network and penetrates and crosslinks with each other, so that the modification presents a high polymer performance; After the film is dry, keep the rubber elastic and flexible at low temperature; It has strong shear resistance and can withstand the long-term load of the bridge deck and compression requirements, which can prevent structural damage caused by water seepage and delay the service life of highway bridges. It is the most ideal waterproof material for bridge deck, and can also be used for waterproof, anti-seepage, anti-corrosion wall Waterproof and moisture-proof. The waterproof material not only has good waterproof performance, but also can absorb the stress and noise of the road and bridge deck as the stress absorption layer; Because it has certain elastic and plastic deformation capacity, it can bear the load without being damaged. Alleviate the aging of road and bridge pavement and delay the service life.
2、 Product characteristics
1. Excellent heat resistance, its composition and performance will not change at the set paving temperature of asphalt concrete.
2. It still has good flexibility in cold climate.
3. The waterproof layer is located between the concrete and asphalt concrete, which has good bonding performance cement The concrete is bonded into a unified whole.
4. It has high tensile strength and deformation resistance, and can withstand the impact of load and structural deformation.
5. The waterproof layer has good anti-aging performance.
3、 Scope of application
It is applicable to bridge deck waterproof layer, highway bridge, urban overpass, railway bridge, bridge and culvert and other bridge deck waterproof layer projects.
4、 Construction technology
1. Machine spraying and manual brushing.
2. Preparation of construction tools: the mixing bucket, spraying machine or special bristle brush shall be prepared before construction.
3. Base course requirements: the strength of bridge deck and beam concrete shall reach the design mark, and the surface shall be free of loose laitance, peeling, hollowing and serious cracking. The surface flatness shall meet the requirements of bridge specifications. The elevation of the upper opening of the vertical drainage pipe shall be lower than the elevation of the base layer. The drainage outlet must be firmly installed with the base layer without any looseness.
4. The waterproof base shall be clean, dry and free from ponding.
5. Base course treatment: the bridge deck shall be free of dust, floating ash, impurities, oil stains, etc. Before the waterproof layer is paved, the surface can be cleaned by air compressor, water purification, degreasing agent, etc. If there are hard sundries such as concrete, mortar, etc., they should be polished off.
5、 Packaging, storage and transportation
50kg plastic bucket or 200kg iron bucket.
It is non-toxic and nonflammable, and can be transported by general transportation mode.
The storage period is 6 months, which should be stored in a warehouse above 0 ℃, and the sun exposure should be avoided in summer.
