Introduction to anti-crack stickers:

Anti-crack stickers (also known as anti-crack stickers) are compounded by asphalt-based polymers, high-strength tensile tire bases, and high-strength fabrics that are resistant to high temperatures and compatible with asphalt. Sticking it on the asphalt concrete surface that has cracks or spalling can reduce and block the temperature and shrinkage stress that it acts on the road surface, so it also reduces the tendency of cracks to reflect through the surface layer. Layers are isolated so that the upper layer is free from multi-directional displacement and shear stress, used for roads, bridges, airports, etc.

Anti-crack features:

1. The construction is convenient and the construction efficiency is high.
2. It is not affected by the season and can be constructed in all seasons.
3. Performance indicators can be customized and processed according to customer requirements.

Main properties of anti-crack stickers:

1. Isolation effect. Laying anti-cracking stickers isolates the cracked surface from the asphalt surface, avoiding direct contact between the cracked surface and the asphalt surface, and the tensile stress of the base crack can‘t be directly transmitted to the asphalt concrete surface, although reducing the However, the high polymer anti-cracking paste can make the upper and lower layers well adhered into a whole, and jointly bear the load of the vehicle, which is enough to prevent the relative displacement of the upper and lower layers of the interface and maintain continuity.

2. Reinforcing effect. The anti-crack sticker has a certain strength and can bear a certain crack tensile stress. When the crack tensile stress increases and is greater than the tensile strength of the crack-resistant sticker, the crack-resistant sticker begins to deform, and the surface layer begins to bear the transmission of the crack-resistant sticker’s Upcoming tensile stress. The layer of anti-crack paste will bear all the tensile stress of the crack. Obviously, the anti-crack paste plays the role of reinforcement. In this sense, it improves the tensile strength of the pavement structure layer.

3. Energy dissipation and buffering effect. The anti-cracking sticker is a material with certain extensibility. The polymer has good low-temperature flexibility. It is laid between the asphalt pavement layers, which is equivalent to setting up an elastic layer. The crack tensile stress of the base layer is extended to the Wider range, so as to relieve the stress intensity at the crack, and the elastic interlayer can absorb part of the tensile energy.

4. Water-proof and anti-seepage effect. The anti-cracking high polymer can form a complete water-proof and anti-seepage layer, which can block the penetration of water from the road surface to the roadbed, thereby protecting the strength of the base layer and preventing the properties of the base material from further deteriorating. Anti-cracking stickers used in asphalt pavement layers can effectively inhibit the upward transmission of cracks, and play the anti-cracking and energy-absorbing functions of anti-cracking stickers in actual engineering.

Anti-crack technical indicators:

Construction guidance for anti-crack paste:

1. Choose the specification of the anti-crack stickers according to the width of the cracks on the pavement, usually there are three kinds of 25cm, 33cm, and 50cm (can also be customized according to customer requirements); for cracks wider than 5mm, choose at least 33cm anti-crack stickers; for cracks below 5mm Choose an anti-cracking sticker of at least 25cm.

2. Use electric brushes and hair dryers to clean the cracks choose to use anti-crack stickers. The surface of the cracks must be flat (the cracks with a width greater than 5mm must be filled with polymer sealant first), without large protrusions, depressions, loose, gravel or Oil marks, grease, and other dirt; large potholes must be filled.

3. Peel off the release paper on the back of the anti-cracking sticker, with the non-adhesive side facing up, and stick the anti-cracking sticker on the road evenly with the crack as the center line. When the temperature is lower than 0°C, it needs to be glued or baked before pasting.

4. In case of irregular cracks, use a paper-knife or scissors to cut off the anti-crack stickers, and follow the direction of the cracks to paste. However, at the junction of the anti-crack sticker and the anti-crack sticker, an overlap of 50-60mm should be formed.

5. Use a roller to roll hard, and iron the anti-crack sticker to the ground to ensure that the anti-crack sticker is integrated with the road surface without air bubbles or wrinkles.

6. After the construction of the anti-crack paste on the base layer is completed, try to protect the completed road surface to avoid pollution and damage to the surface of the anti-crack paste.

7. Spray a sticky layer of oil and overcoat mixture.

Environmental conditions for using anti-crack stickers:

1. It should be used under the condition that the surface temperature is equal to or higher than 20 ℃, and its self-adhesive effect is better.

2. If the surface temperature is lower than 20°C, it is recommended to use a warm fire to bake the rubber surface of the anti-cracking sticker. Be careful not to overbake it, and the glue surface will melt. Or use conventional emulsified viscous oil, the dosage is 0.5-1.0kg/m2.
