Product Details:

Sealing tape (or road sealing tape, pavement tape, pressure seam tape, seam sealing tape, crack tape, road band-aid, and surface layer tape) is a composite geotechnical technology developed and produced by our company specifically for road crack management. Material. It has many advantages such as good wear resistance, strong tensile strength, strong water sealing ability, low cost, beautiful and durable, and simple construction.

Since the causes, shapes, and degrees of cracks on the road surface are very complex, road surface layer tape comes with various specifications to meet on-site use. They are roughly divided into wide joints (mainly horizontal joints), narrow joints (mainly longitudinal joints), and three types of network cracks. Wide cracks are mainly reflective cracks. Generally, laminated cracks with a width of 15 cm are used. Because the cracks are wide, the cracks should be filled first and then laid; narrow cracks are mostly construction joints of asphalt mixtures, and the width is relatively narrow. Generally, surface seam tape with a width of 8 cm can be laid directly. The cause of network cracks (including cracks and other irregular cracks) must be analyzed.

There is no need for equipment to expand the seam when laying the seam tape. It is a non-damaging crack treatment technology. It is simple and fast and can be opened to traffic after being passed anytime and anywhere, instantly preventing the damage caused by cracks in the road. It can turn at will according to the direction of the crack and can be 100% Sealed along the cracks to ensure the sealing quality; it is suitable for areas with large temperature differences. When the road surface is high, this product will not contaminate the road surface by being squeezed out or being rolled away by wheels. The conventional widths of seam tapes are 15 cm, 8 cm, 5 cm, and 3 cm. They can be cut or spliced on site according to the crack width and actual crack resistance needs or can be customized as required.

The main structure of the pavement seam tape is divided into four layers, from bottom to top: 1. High-adhesion material layer, 2. High-elastic polyester layer, 3. Polymer elastic material layer, 4. Tear-resistant imported non-woven cloth or flexible polyethylene layer. The four layers of materials play different roles respectively. They are composed of four layers through a special process. The first layer plays an excellent bonding role to prevent the formation of gaps between the material and the road surface and prevent water from entering. The second layer plays a role in cracking the temperature. When the width changes under the influence, it plays the role of skeleton and elastic recovery, which is equivalent to the steel hinge line in the hollow plate. However, this layer of material not only has strength but also has a certain elasticity. The third layer is a polymer material, which not only has excellent high and low-temperature properties, but also has good elasticity, and is the main functional layer. The fourth layer is covered with hot-rolled cloth according to customer requirements, which can reduce the friction coefficient of the road surface caused by seams and stabilize the movement of the material or the friction loss of the wheels.

Advantages of seam tape

1. High-tech products and quality assurance. Because the surface layer joint tape is a special product developed specifically for pavement cracks, the development ideas eliminate the shortcomings and deficiencies of joint filling. During the development process, we also received guidance from highway research departments and foreign experts. After years of market testing, it has been widely recognized.
2. The bonding is firm and not easy to fall off. Because the layer of the surface seam tape in contact with the road surface is a layer of highly dense material, it is not only not easy to fall off after being bonded to the road surface, but also difficult to remove even if it is separated manually, effectively ensuring the effect.
3. Good high and low-temperature performance. The main functional layer of the surface seam tape is a polymer material, coupled with a mesh-shaped high-strength and high-elastic polyester layer, which can absorb part of the material so that the overall material does not flow at high temperatures and is not brittle at low temperatures.
4. Unique “self-healing” function. It can heal minor puncture damage by itself and can automatically fill and heal minor cracks.
5. Excellent durability. After years of market research, it has been found that the repaired pavement can maintain no cracking, movement, or damage for more than one year. Only a few cracks are caused by crack misalignment due to damage to the function of the base layer, but they are still well-bonded.
6. It can effectively treat radioactive cracks and bifurcation cracks. Because the surface layer seam tape can be tailored according to the overall width of the crack, it can completely cover the crack area without causing water seepage due to leakage.
7. Convenient construction. No equipment is required, just a small car and two people can do the construction. Construction workers also do not need professional training.
8. No material waste. Because the material does not need to be heated, it can be pasted immediately after use, and the seam can be pasted as long as it needs to be, without material loss.
9. No equipment investment. No equipment is required during construction.
10. Fast construction speed. You can seize favorable construction opportunities. Without any equipment, a large number of manpower can be organized to complete the construction tasks in a short time during the favorable construction season and seize the favorable opportunity.
11. The construction technology is simple and the construction is safe. During the construction process, there will be no pollution to the environment and no harm to workers.

Main uses of seam tape:

This product is suitable for treating various cracks in cement, steel plates, asphalt pavements, small potholes, and well covers, including reflective cracks. It can also be used to treat cracks before construction such as sealing covers. Prevent and control loose cracks, water seepage, edge collapse, seam collapse, and pits.

Construction technology of seam tape

1. Select the specifications of the joint tape used according to the width of the pavement crack (joint) joint. There are usually three types: 8cm, 5cm, and 3cm.
2. Use an electric brush or hair dryer to clean the cracks (joints) where the seam tape is used. The crack surface must be smooth (cracks with a width greater than 5mm must be filled with polymer sealant first), and there should be no large protrusions, depressions, or looseness, gravel or traces of oil, grease, and other dirt; if there are any large potholes, they must be filled.
3. Peel off the isolation paper on the back of the seam tape, with the non-adhesive side facing up, and stick the seam tape flatly on the road with the crack (joint) seam as the center line. In the Northeast and Northwest regions, when the temperature is lower than 15°C, glue should be applied first or a mixture of diesel and gasoline (diesel and gasoline ratio 1:1) should be applied to both sides of the crack before pasting.
4. If you encounter irregular cracks (joints), you can use a paper-knife or scissors to cut off the seam tape, and follow the direction of the cracks (joints) and paste them. However, at the junction of the seam tape and the seam tape, an overlap of 80-100mm should be formed.
5. Use a roller to press hard and iron the seam tape to the ground to ensure that the seam tape is integrated with the road surface and there are no bubbles or wrinkles.
6. After the construction of the joint tape is completed, try to protect the completed road surface to avoid contamination and damage to the surface of the joint tape.
7. Traffic can be open.

Single film seam tape

 

Single-film seam tape is mainly used for crack sealing and waterproof repair of highways, national highways, municipal roads, rural roads, residential areas, and other roads.

 

Single film seam tape is a strip of material in a sandwich shape, that is, the protective films on both sides sandwich the special material in the middle. The structure is three-layered. The upper layer is a micron-level protective film. This layer of protective film will automatically weather and crumble after some time after construction and integrate with the road surface. In the middle is an active ingredient with a thickness of 2-4mm, which is secretly modified asphalt. After construction, it will gradually embed in the cracks and gaps in the road surface and form an integral part of the road surface. After some time, the phenomenon of rising above the road surface will disappear. There is also a micron-level protective film underneath. This layer of protective film is different from the upper layer. It is relatively thick and hard. During construction, it can be peeled off while pasting. It is easy to peel off and not easy to break.

 

The active ingredient of the single-membrane seam tape is secretly modified asphalt, which is made of 70# or above heavy traffic petroleum asphalt, imported modifiers, and other special materials. It is processed through a special process according to the secret formula.

 

 

The single-membrane seam tape has been tested in many places and environments during the research and development stage. Therefore, since its launch, since it is used to repair road cracks, it does not crack in winter and does not flow in summer. It can be driven and rolled over sometime at temperatures above 20°C. It can be completely embedded into the road surface and restore the smoothness of the road surface, which has been well received by a large number of users.

Storage of single film seam tape

There are three points to note when storing single-film seam tape:

1. To ensure good adhesion of the seam tape, store it in a cool place in summer and in a sunny or heat-insulating place in winter. The general storage temperature is between 15℃-35℃;
2. Avoid storing in humid places to prevent damage to the packaging;
3. According to the quality requirements of the packaging boxes, they should not be stacked too high, and heavy objects should not be stacked above to prevent the packaging boxes from being crushed, which will cause the single film seam tape to be squeezed, deformed, and bonded.

Acceptance of single film seam tape

The acceptance of single-film seam tape is divided into apparent acceptance and index acceptance. Apparent acceptance includes appearance, visual adhesion, width, length and thickness;

Appearance acceptance: Appearance acceptance mainly includes whether the shape of packaging and road pavement asphalt seam tape is seriously squeezed or damaged; acceptance of width, length, and thickness can be spot-checked with vernier calipers and tape measures according to contract requirements; the bonding force is the bonded object. Generally, you can use your fingers to press the asphalt seam tape on the road surface, and then lift it. It is advisable that your fingers can stick to the single film seam tape for more than 10 centimeters (cm) and maintain it for more than 1 minute, as shown in the figure below:
