Why is pavement joint tape called pavement band-aid?

Pavement joint tape is used to repair pavement cracks (cracks) and plays a role in sealing and waterproofing; Band-AIDS are used to repair wounds on human skin. The medicinal components on the band-aid can effectively treat wounds and promote wound healing. Perhaps this is why the pavement band is also called the pavement band-aid. Because road band-AIDS are used to repair road cracks. However, there are many varieties and materials, and most of them now have tire base cloth, which is almost impossible to combine with the road surface and will cause traffic. The adhesion ability of tire-free base fabric is better.

Relatively speaking, it is more difficult to produce base fabric without tire. Repair small cracks on the road with band-aid. Band-aid is applied to road construction, with vivid metaphor, remarkable effect and low cost. When people are least hurt, it has the same effect. Recently, the provincial highway 102 in our city is on the highway from the west of the route to Yulingguan. As long as there are small cracks, black tape is stuck on the road surface, just like sticking a band-aid on the wound. It turned out that the maintenance workers of Changhua Highway took advantage of the fine weather to repair the pavement cracks. At the scene, I saw the workers clean up the cracks on the pavement first, and then tear off the isolation film of the "road band-aid" and stick it directly on the surface of the cracks. In the process of pasting, they can directly step on it with their feet. The whole process is simple and easy. Compared with the traditional road crack repair technology, it reduces the working time of crack repair and improves the working efficiency. Without the previous mechanical equipment such as slotting machine, the whole construction is very flexible and fast. Band-aid for pavement is mainly used to repair cracks on expressway pavement. It is a strip material made of modified asphalt or modified asphalt and fiber as the main raw materials. It has the characteristics of softness, flexibility, strong cohesiveness and strong weather resistance. Covering small cracks with Jiage pavement band-aid can form a dense connector with the crack area, which can effectively achieve the effect of stopping water, prevent rain and other debris from entering the subgrade along the crack, and prevent the crack area from loosening, edge collapse, cracks and pits.
