Rapid-Drying Cement for Airport Pavement Slab Replacement in the Airfield Area

Concrete pavement surfaces may develop cracks, potholes, exposed aggregates, joint misalignments, and fragmentation due to factors such as surface loads, rainwater, and corrosion from chemical products like deicing agents, either during initial use or after a period of service.

When such damages occur on airport runways, timely repair is essential. Otherwise, continued exposure to loads and environmental factors will rapidly degrade the pavement's performance, further reduce its load-bearing capacity, accelerate structural failure, disrupt normal operations, and even pose risks to vehicles and aircraft. Prompt repair during the early stages of damage not only extends the pavement's service life but also reduces overall maintenance costs and ensures normal operation.
