Tai'an Zhengze Engineering Materials Co., Ltd., relying on years of experience and customer feedback, constantly improves and perfects road maintenance materials such as crack resistant stickers to maximize the main functions of this material. The company is willing to accept good advice, and hopes that all colleagues engaged in road engineering will constantly put forward valuable suggestions for the company to improve. We will explain the main properties of this material for road crack prevention and waterproofing summarized after the current road use of anti crack sticker:
1. Physical performance: anti crack sticker is a kind of active waterproof material with degree, elongation and cohesiveness. Its net thickness is more than 1.2 mm, which can improve the pavement crack waterproof performance.
2. Chemical property: The anti crack sticker is composed of a variety of molecular materials, with stable chemical property and * * * performance. It has * * * better chemical property than previous geotechnical materials.
3. Bonding performance: the anti crack sticker has a strong bonding ability and can be directly bonded with the clean base course.
4. High elasticity and strong deformability: the anti crack sticker has the ability of "self-healing" and strong deformability, and will not break or tear when the base crack moves up and down.
5. Pushing capacity: the anti crack sticker is laid at the crack with stress concentration, and has strong elasticity, asphalt The aggregate of the mixture will form a certain degree of inlay with the anti crack sticker, which is not easy to slide on the surface of the anti crack sticker, so it will not cause lateral displacement.
6. Waterproof performance: anti crack sticker is mainly used for stress concentration and crack sealing at the crack to form a waterstop, which is usually used for road anti crack reinforcement Geogrid Not waterproof, Geotextile The function of the crack is also a surface, but the crack is not strengthened, forming a weak link in the crack, which is easy to cause damage, fracture, poor cohesiveness, water seepage and other phenomena.
7. Construction performance: the anti crack sticker is convenient for construction, and it can be heated in cold construction, and it can be fastened once pasted.
8. Temperature and low-temperature performance: the anti crack sticker is mainly composed of polymers, which has good low-temperature performance and certain thickness. It also forms a good bond with the base course. It can also play a cooling role when paving the surface course. Although the instantaneous temperature of asphalt mixture is relatively high during paving, the anti crack sticker will not be damaged.
