The concrete pavement of the airport is directly related to the safety of aircraft takeoff and landing and the safety of vehicle passage within the airport area, and has extremely high requirements for structural strength, durability, and construction quality.
During the construction and long-term operation process, various types of cracks and diseases are easily generated on the pavement due to the influence of loads, temperature changes, foundation conditions, construction processes, and environmental factors.
If not treated in a timely manner, they will continue to expand and deteriorate, causing secondary problems such as water seepage and erosion, base detachment, and panel fragmentation, laying hidden safety hazards for operation.
The main causes of pavement cracks are internal structural factors and external environmental load factors.
Large area concrete hydration temperature difference and shrinkage deformation can also induce early cracking.
This article combines the actual operation and maintenance of airport runway, sorts out the formation mechanism of various typical cracks, proposes targeted technical solutions for source prevention and disease repair, and introduces the application advantages of special grouting materials in combination with daily maintenance conditions, providing practical reference for the maintenance and treatment of airport concrete pavement.
