Zhejiang Wenzhou Highway Anti Crack Patch Road Anti Crack Patch Yiwu Market

Description :

　　Construction process of crack prevention sticker:

　　Cracks or pits with a width exceeding 1cm must be cleaned first, then filled and compacted with adhesive sand or hot asphalt mixture to the existing height, and then sealed with crack resistant stickers.

　　Taking the expansion joint (crack) as the center, according to the design requirements, select the crack prevention sticker and unfold it according to the width. Arrange it at the location where crack prevention is to be done, with one side of the isolation paper facing downwards. Then lift the crack prevention sticker in place halfway and tear off the isolation paper below while laying it forward, so that the crack prevention sticker is laid flat on the original base surface.

　　Construction precautions:

　　1. The cement concrete pavement must be dry before construction. Construction shall not be carried out on damp substrates or in rainy or snowy weather.

　　2. After construction, it is necessary to use sandbags or rubber tire rollers to compact the "crack prevention sticker" to prevent rainwater from entering the bonding surface of the "crack prevention sticker" before paving asphalt concrete. If it is expected to rain heavily before paving asphalt concrete, sealant should be used to seal both sides of the "crack prevention patch".

　　3. Construction should not be carried out when the temperature is below 5 ℃.

　　4. Vehicles are not allowed to roll or turn around on the "crack prevention sticker" during asphalt concrete paving.

　　5. When the slope is greater than 5%, the width of the "crack prevention patch" should not exceed 330mm. When laying the bottom layer of asphalt concrete, there may be a small amount of slippage, which should be repaired in a timely manner to avoid affecting the quality of the project.

　　6. The total thickness of asphalt concrete paving should not be less than 6cm.

　　7. When the height difference between adjacent edges of the "crack prevention sticker" is greater than 1cm or there are many potholes, the part should be leveled before tiling to prevent the "crack prevention sticker" placed in the depression from being damaged by gravity. The leveling material can be epoxy mortar or asphalt mixture.
