What is the function of road crack sealing tape?
2 Answers
Ground crack sealing tape can effectively prevent rainwater from further eroding the base layer through cracks. During the construction of asphalt pavements, especially in mountainous road projects, high embankments and deep cuts are common practices to improve road technical standards. The uses of crack sealing tape: Road crack sealing tape is mainly used for maintenance projects such as crack repair on highways, general roads, and urban municipal roads, as well as for bonding layers between new and old pavement surfaces. Types of road crack sealing tape: Road crack sealing tape is categorized into normal-temperature type, low-temperature type, and extreme-cold type. The normal-temperature type is suitable for regions with temperatures as low as -20 degrees Celsius. The low-temperature type is suitable for areas with temperatures down to -30 degrees Celsius, while the extreme-cold type is designed for regions experiencing temperatures as low as -40 degrees Celsius. Customers can choose the appropriate type based on local temperature conditions when purchasing.
The most direct effect of using highway crack sealing tape is to seal small cracks on the road surface, preventing water and debris from seeping in and damaging the underlying structure. For example, when we drive over areas with cracks, water that gets inside can freeze and expand in winter or accumulate and corrode the pavement in summer, leading to more potholes or severe damage. The sealing tape forms a waterproof layer, slowing pavement deterioration and extending its lifespan by several years. With smoother roads, driving becomes safer and more stable, tires are less prone to damage, and the likelihood of accidents decreases. Road maintenance departments also benefit by saving time and costs, avoiding frequent major repairs. From a practical perspective, this method is economical, efficient, and reliable, making it worth promoting for use on urban streets and highways.
