Rapid Treatment Methods for Airport Pavement Diseases
When diseases occur on airport pavement, the traditional treatment process involves first analyzing the cause of the disease, determining its scope and severity, and then carrying out treatment based on the situation. If the disease is not severe, such as minor cracks, grouting methods or repair materials are used; if the disease is severe, such as large-scale fragmentation, the original pavement and waste materials are removed, and concrete of the same strength grade is used for cast-in-place repair until curing is completed. Traditional treatment solutions not only affect airport operations but also reduce the bonding between new and old concrete pavements. With the emergence of new technologies and materials, polymer rapid repair methods have come into being.
Rapid-curing, winter construction-capable polymer rapid repair material Polymer rapid repair material is a specialized material for airport pavement repair, made from resin as the raw material, mixed with an appropriate amount of fiber, high-strength aggregate, and various additives. It is suitable for different airport pavements, such as broken slabs, edge drop-offs, corner drop-offs, slab fractures, local damage, bridge expansion joints, concrete and asphalt pavements, and other damaged areas that require rapid reopening to traffic.
Performance Advantages:
1. Environmentally friendly, lower emissions, safer and more eco-friendly;
2. No shrinkage after curing, high stone strength, good durability, no aging, excellent impermeability;
3. Fast curing time, cures and opens to traffic in 30 minutes in summer and 60 minutes in winter;
4. Not limited by temperature, construction can be carried out year-round, even at low temperatures of -50°C, completely solving the problem of inability to construct in winter and northern regions;
5. Simple construction process, easy operation, suitable for large-scale use;
6. Suitable for emergency repairs and timely treatment of pavement diseases;
7. Excellent chemical and pollution resistance, with outstanding resistance to acids, alkalis, and other chemicals;
8. High strength, excellent wear and impact resistance, excellent adhesion, not prone to peeling like epoxy resin. One-hour compressive strength exceeds 40MPa, flexural strength exceeds 15MPa, and bond strength exceeds 3.7MPa;
9. Non-absorbent, no damage or strength reduction in winter.
10. The product is packaged as a kit, with 5kg packages of MMA polymer rapid repair material—emergency repair buckets include tools, and no additional auxiliary tools are needed for construction.
To date, this material has been widely used in over 300 military and civil airports across the country and has received positive feedback from users. The application of polymer rapid repair material enables the repair of airport pavement diseases without halting flights, greatly improving airport operational efficiency and safety.
Conclusion Timely treatment of airport pavement diseases is crucial for ensuring flight safety.The emergence of polymer rapid repair material provides an effective solution for the rapid repair of airport pavement diseases. By adopting this advanced material and technology, pavement diseases can be repaired in the shortest possible time, ensuring normal airport operations. It is hoped that more innovative technologies and materials will be applied to the maintenance and repair of airport pavements in the future, providing a more solid guarantee for the safety and smoothness of air transport.
