Do I need to make a groove when repairing road cracks with pavement tape?

Please note that there is no need to make grooves when repairing road cracks with Jag Pavement Tape. Of course, it is best to repair pavement cracks without slotting, because slotting and expanding joints will cause secondary damage to the pavement and reduce the performance of pavement use. Because the road surface cracks are not parallel, most of them have more bends and branches, the slotting machine can not be well slotted with the direction of the crack, and some bending angles in the direction of a crack can not be realized, so the slotting machine tooth only extends from the first end of the crack through the good road surface to the end of the crack, so that the good road surface damage is produced.

It should not be used, the 4 cm wide seam tape used in the factory last month is not slotted anyway, so it is directly pasted, but the cracks need to be cleaned, no big bulges, depressions, loose, gravel marks, grease, and keep the crack surface clean and dry, the cracks must be dry, the spring rain is more than the road surface may be dry There may be moisture in the cracks, it is easy to cause the seam tape to fall off, in order to ensure the construction effect needs to be more than a few days before construction, Huatong seam tape is good, The tubeless asphalt-based material has a large viscosity and better compatibility with the road surface, and the vehicle is gradually deformed and squeezed into the cracks independently, and the sealing cracks are not seepage, and the asphalt pavement is better integrated. However, if the crack is more than 2cm, it is still recommended to use cold fill glue or cold patch material for treatment

Due to weather and climate restrictions, it is not suitable for construction before rain, because the cracks on the pavement after the construction have not been fully rolled by driving, and the road surface has not been fully combined, once the rain seeps in, the seam tape is easy to fall off. After the rain stops, it is necessary to wait for the cracks to dry before using the crack tape for construction, otherwise the water in the crack will not evaporate, and the tape will easily fall off.

Asphalt road tape is used to repair small cracks in the road surface, and it is very simple to use. For example, the construction of Jiage asphalt road seam belt can be completed in only four steps: cleaning, tearing film, pasting, and stepping on it to open to traffic.

However, two points need to be noted: there should be no rain for 24 hours before and after construction, and the cleanliness of the cracks before pasting should be ensured.

If you don't use it, I use the jag sticker tape tear film and paste it.

1) To clean the joint, the old caulking material and the sand and mud mixed in the joint should be removed by a sewing machine, and then the pressure water and compressed air with pressure greater than or equal to the joint should be used to completely remove the dust and other pollutants in the joint to ensure that the joint wall and the interior are clean and dry. The seam wall inspection is based on the standard of not wiping off the dust. After the seam is cleaned, the seam wall is straight, and the seam width is not more than 2mm wider than the original seam.

2) Caulking: AWhen using room temperature polyurethane caulk, the two-component material should be mixed evenly according to the specified proportion according to the 1h caulking amount.

b.The depth of the joint should be 15 20mm, and the shallowest should not be less than 15mm. First, squeeze and insert the 9 12mm diameter porous foam backing strip, and then fill the joints of the blind stool.

The top surface of the joint should be flush with the plate surface in hot weather. In cold weather, it should be filled with a concave liquid level, and the center is 1 2mm lower than the surface of the key plate. The caulking must be full, uniform, consistent and continuous, and the caulking material must not be missing, cracked and water seepage.

3) Health preservation, the health period of the normal temperature construction caulk should be 24h on low temperature days, 12h on high temperature days, and traffic should be closed during the health care period of grout materials. If the width of the longitudinal and horizontal joints is greater than 1cm, the method of cleaning the seams, setting up seam plates or caulking strips, and caulking shall be adopted. The seam board is made of cork board or polyurethane rigid foam board.

Asphalt road seam tape is a kind of repair material for road cracks, which is mainly asphalt-based, and is more suitable for use in asphalt pavement.

Asphalt seam tape is a black strip of long strip material, high cohesiveness, simple construction, usually when dealing with asphalt pavement cracks, as long as the road surface is cleaned, in the case of keeping the road clean and dry, the asphalt road seam with the adhesive side down, with the crack as the center of the paste, while sticking with the foot firm, once pasted basically will not be separated from the road surface due to external force, the service life is generally about 3 years.

The advantage of asphalt road joint tape is that it is convenient to construct and does not need special treatment for cracks, which is an obvious advantage in the construction of asphalt joint tape without slotting compared with joint filling glue; The thickness also avoids the embarrassment of jumping out of the vehicle after acting on the road. The only point is that it doesn't look very beautiful, and it can't do the beautiful joint filling of Yantai Huatong cold filling glue.

The asphalt road joint belt construction must pay attention to the construction of the road surface needs to be kept clean and dry, before and after the rain can not be constructed, when the road surface is pasted, we must pay attention to the asphalt road joint belt at the beginning of the focus of the compaction; The material can not be stretched hard during construction, and it is recommended to use it above 15 for better results.

1. The pavement seam with sealing is very simple

Convenient. The use of surface layer DU seam tape on the surface of asphalt pavement only needs to be cleaned to glue, eliminating the need for traditional heating equipment for caulking DAO.

2. The quality of the Jiage pavement seam tape is reliable and beautiful and durable. The use of pavement seam tape sealing can keep the road surface from deformation and brittleness, and not be brought up by the wheels, effectively prevent the cracks on the road surface, and overcome the phenomenon of gnawing edges after slotting and filling. Adapting to areas with large temperature differences, this product will not be extruded and run over by wheels when the road surface is hot.

3. The construction speed of using pavement seam tape sealing is fast, which is several times that of grouting. No equipment is required for joint expansion. It is a non-damaging crack treatment technology; Simple and fast, anytime, anywhere, after pasting, it can be opened to traffic, and immediately prevent the damage caused by cracks to the road.

4. The use of pavement seam tape sealing can be turned at will with the direction of cracks, and 100% can be sealed along the cracks to ensure the quality of sealing.

5. The use of pavement seam tape sealing does not require mechanical equipment to groove, nor does it need to heat the joint filling material, which is safe and environmentally friendly, and non-toxic to construction personnel.
