Asphalt sealant material for concrete pavement

　　Road surface sealant - sealant

　　Road surface grouting construction is to eliminate road surface diseases in their early stages and achieve preventive maintenance. Based on my own work experience, when using a joint filling machine to fill road joints, I should adhere to the principle of filling as soon as possible, ensuring that every crack is not missed and preventing any leakage. Inject after slotting the crackcrack sealantBefore opening the slot, it is necessary to clean the joint thoroughly to avoid loose adhesion between the sealant and the road surface, which may cause cracking or detachment. A high-pressure dust blower should be used to blow away the dust and soil in the groove to ensure that the sealant is in contact with the road surface, increase the adhesion force, and achieve good sealant effect, which can be full, smooth, clean, and beautiful; Construction is basically not affected by temperature and can be carried out at low temperatures; The construction method is simple, easy to operate and master; Grouting adhesive has better quality and longer service life compared to hot asphalt grouting. Using this equipment and process for grouting once can maintain the road surface for two years without the need for further grouting. Compared with traditional hot asphalt manual grouting once a year, it reduces the overall cost.

　　At the same time, summarize the following key points of sealant construction:

　　（1） Considering the 14% shrinkage of the sealant and the need for preheating, it is advisable to construct it at a temperature of 0 ℃.

　　（2） The main bonding surface between sealant and road surface is the two side walls of the crack, so the cleaning of the side walls is necessary.

　　（3） Determine the grouting speed and the amount of grouting adhesive to be used based on the diameter of the grouting pavement material and the roughness of the pavement surface during cutting.

　　（4） The road surface with network cracks should not be treated with this method. With better experience in grouting in future work, the use of grouting adhesive for asphalt concrete pavement grouting treatment not only has certain advantages in grouting quality, service life, maintenance cost, etc., but also has good prospects for promotion and application in daily highway maintenance.
