JTB-207 Rapid Repair Mortar for Concrete Pavement is a specially formulated repair material designed for the rapid restoration of distressed concrete pavements, including pitting, delamination, surface scaling, spalling, cracking, and exposed reinforcement. It enables a short construction window, allowing traffic reopening within two hours after application.
• High bonding strength
• High durability & aging resistance
• High compressive strength
• High flowability, waterproof & corrosion resistant
• Eco-friendly, suitable for repairs
• Timely repair of rough, hollow, scaling, spalling, cracking, and exposed-rebar concrete pavements
• Surface preparation: Remove the loose parts of bulging, peeling, cracking and other areas. For areas with less than 3mm, overly flat areas and areas with oil stains, roughen them up. Thoroughly moisten the base surface with clean water, but there should be no standing water, or directly apply the JTB Interface Bonding Agent evenly.
• Mixing and stirring: Mix the material with water and stir it. Follow the 28% water-to-material ratio. Add water while stirring material. During the stirring process, ensure thorough and uniform mixing. The recommended duration is about 3 minutes.
• Construction: According to the working surface and construction progress, the materials mixed each time should be completed within 20 minutes.
• Maintenance: After the initial setting of the construction surface, water (spray) maintenance is required. For horizontal ground, it should also be covered with damp gunny bags, etc. Maintenance should be carried out in an environment of 5-40℃.
