Self-adhesive seam tape (also known as road seam tape, seam strip, road bonding tape, joint tape, crack sealant, road bandage, surface bonding tape) is a composite geosynthetic material used for road crack treatment. It boasts numerous advantages such as excellent wear resistance, strong tensile strength, excellent water-sealing properties, low cost, aesthetic durability, and simple installation.
Due to the complexity of the causes, shapes, and extents of surface cracks, various sizes of crack filling strips are available to meet on-site needs. They are generally categorized into wide cracks (mainly transverse), narrow cracks (mainly longitudinal), and network cracks. Wide cracks are primarily reflective cracks, typically requiring a 15 cm wide surface crack filling strip. Since the cracks are wide, they should be sealed first before laying. Narrow cracks are usually construction joints in asphalt mixtures, narrower in width, and generally can be directly laid with a 8 cm wide surface crack filling strip. For network cracks (including alligator cracks and other irregular cracks), a cause analysis is necessary.
Laying self-adhesive crack sealing tape without expansion equipment is a non-destructive crack treatment technique; it's simple and quick, allowing for immediate traffic flow after application, instantly preventing damage to the road from cracks. The tape can bend around cracks in any direction, ensuring a high-quality seal. It is suitable for areas with large temperature variations; the product will not be extruded or碾走by wheels during high temperatures on the road surface. Standard widths of the tape are 15cm, 8cm, 5cm, and 3cm, and can be cut or spliced on-site according to crack width and crack resistance requirements, or custom-made to order.
Advantages of Non-adhesive Self-adhesive Seaming Tape
1. Tech products, with peace of mind quality. As the non-tire self-adhesive seam tape is a specialized product designed for road cracks, it eliminates the disadvantages and shortcomings of sealing from the outset. Developed with guidance from highway research departments and international experts, it has undergone years of market testing and gained widespread recognition.
2. Strong bonding, not prone to peeling off. The layer in contact with the road is a high-adhesive material layer, ensuring that it doesn't easily come off after bonding with the road surface. It's even difficult to peel off manually, effectively guaranteeing the effect.
3. Excellent high and low temperature performance. The main functional layer of the seam tape is a high polymer material, supplemented by a mesh-like high strength and high elasticity polyester layer that absorbs a portion of the material, ensuring the overall material does not flow at high temperatures or crack at low temperatures.
4. Unique "Self-healing" feature. Capable of autonomously repairing minor puncture damages and automatically filling and healing minor cracks.
5. Excellent durability. After years of market research, it can maintain integrity without cracking, shifting, or damage for over a year. Only a few cases have experienced cracking due to sub-layer functional failure, but they still adhere well.
6. Effectively treats radioactive and fissured cracks. Since the surface joint tape can be custom-made according to the total width of the cracks, it can fully cover the crack area without any gaps, preventing water leakage.
7. Easy to install. No special equipment needed; just a small vehicle and two people can handle the installation. No pre-job training required for installers.
8. No material waste. As materials don't require heating and are applied as needed, only the length that is sewn is applied, resulting in zero material loss.
9. No equipment investment required. No equipment is needed during the construction process.
10. Fast construction speed. Can seize favorable construction opportunities. Since no equipment is required, a large workforce can be organized to complete construction tasks in a short time during the favorable construction season, thus capturing advantageous opportunities.
11. Construction process is simple. It does not pollute the environment or harm workers during the construction.
