The basic equipment required for road joint sealant construction includes: slotting machine and joint grouting machine. Firstly, the construction workers first use the slotting machine to slotte to ensure that the new bonding surface is exposed, then heat the road joint sealant with the joint sealant to the joint pouring temperature, and evenly pour the materials into the groove with the pressure nozzle of the joint grouting machine. The traffic can be opened 10-20 minutes after the joint pouring is completed.

Firstly, the treatment principle of highway pavement cracks is that the earlier the treatment, the better the effect, the smaller the negative impact and the lower the investment cost. Therefore, the corresponding treatment scheme is usually formulated immediately after the pavement cracks appear; Secondly, the treatment of pavement cracks should be avoided in high or low temperature environment. If the pavement temperature is too high, the solidification and stability time of road joint sealant will be prolonged, the construction quality of joint grouting will be affected, and the road closure time will be prolonged. If the pavement temperature is too low, the bonding effect between the joint sealant and the pavement will be affected.

Road joint sealant breaks the previous history of asphalt to solve pavement problems. Different products can be selected according to different regional and climatic conditions to achieve the expected use effect. It will not melt under high temperature and will not fall off under cold and low temperature conditions.

Road joint sealant can increase the service life of your road by 3-5 years. Now it can be applied to asphalt pavement site, expressway site, national highway and cement pavement.

The use of road joint sealant avoids the situation of efficient and complex construction of other joint grouting materials, uncontrollable temperature of joint grouting materials and poor repair effect. In the whole construction process, there is no need to completely close the road, which meets the needs of smooth traffic and improves the construction efficiency. People from municipal units in Inner Mongolia gave a thumbs up to the road joint sealant.

We all know that nowadays, expressways everywhere have been constantly renovated and constructed, which has opened a broad market prospect for road maintenance products. Under the requirements of future road maintenance market development, road joint sealant will make great contributions to the road maintenance industry.
