Core Points - Ningbo Airport is undergoing its first large-scale runway slab replacement since its relocation in 1991, with the project starting on October 9 and scheduled to last 28 days [1][3] - The runway is critical for the safe operation of the airport, requiring regular maintenance through slab replacement to ensure aircraft safety during takeoff and landing [3] - The new concrete pavement prefabricated assembly maintenance technology is being utilized for the first time in China under non-stop operation conditions, which shortens construction time and reduces maintenance costs [4] Summary by Sections - **Runway Maintenance**: The runway's condition directly impacts flight safety, necessitating periodic maintenance through slab replacement to address wear and minor fractures [3] - **Construction Process**: Work begins after airport closure, with meticulous planning to ensure completion before the next day's flights. The removal of old slabs is labor-intensive and requires careful handling to avoid damaging adjacent slabs [3] - **Innovative Technology**: The new prefabricated assembly technique has been validated through expert consultations and on-site testing, allowing for efficient and safe runway maintenance while minimizing operational disruptions [4]
