How is the anti-crack sticker constructed? Tai'an Tenglu Engineering Materials Co., Ltd. will answer your questions

The anti-crack sticker effectively solves the problem of road cracking, and achieves the durable and beautiful effect of the road. The surface cracks are irregular in shape and complex and changeable, which seriously affects the appearance and waterproof performance of the road surface. The anti-crack stickers for highways can be directly used on the road surface, eliminating the disadvantages of slotting and filling in the past and avoiding secondary damage to the road surface. , suitable for maintenance and construction of roads of different grades. The product is simple in construction, strong in adhesion, wide in working temperature range, long in service life, and closed in cracks.

Anti-crack stickers (also known as anti-crack stickers) are made of asphalt-based macromolecular polymers, high-strength tensile tire bases, and high-strength fabrics that are resistant to high temperatures and are compatible with asphalt. The product is self-adhesive, easy to construct, and can be directly pasted to the crack. This structure is an organic comprehensive application of several measures to prevent cracks on the current road.

First surface treatment

1. Clear the dust and water and other debris on the adhering surface, and keep the road surface dry and clean.

2. Clean up the cracks (joints) with a width of 5-19mm and fill them with sealant.

3. Clean up the cracks (joints) and subsidence areas with a width of 19-50mm, fill them with mortar, sealant or asphalt mixture and compact them to the existing height.

4. Cracks or potholes with a width of more than 50mm should be cleaned first, then filled with mortar or hot asphalt mixture and compacted to the existing height.

5. For the cracks (joints) with different heights and subsidence areas, leveling treatment is carried out.

6. For the protrusions of the bridge deck and road surface, clean or level them until they are smooth.

The second environmental condition

1. It should be used under the condition that the surface temperature is equal to or greater than 21℃.

2. If the surface temperature is lower than 10 ℃, it is recommended to use a warm fire-baked anti-crack sticker, which should be flat, not wrinkled, and not warped.

3. If there is overlap during the laying process, the overlap length is 50mm. There cannot be more than two layers of overlap. 4. It is recommended to roll at least three times with a rubber wheel roller after laying the polymer anti-crack sticker

5. Vehicles can pass after the paving is completed. However, the interval from the laying of the upper layer should not exceed 24 hours.

Then the asphalt overlay

1. After the anti-crack sticker is correctly laid, it should be closely combined with the construction of the upper layer to avoid moisture and rain.

2. After laying anti-crack stickers, you can spread sticky oil such as emulsified asphalt according to the construction specification of hot asphalt mixture. stone or mix.

3. The thickness of the hot asphalt mixture on the anti-crack sticker should be greater than 40mm.
