Frankfurt Airport Shuts Central Runway for 16-Day, 33,000-Tonne FOD-Risk Resurfacing Project

FRANKFURT, Germany — Fraport AG closed Frankfurt Airport’s central runway late Sunday night, launching one of Europe’s largest runway resurfacing projects in recent years and one of the most demanding foreign object debris management operations currently underway at a live commercial airport.

Runway 25C/07C went offline at 23:00 local time on March 8, 2026, immediately after the start of the nightly flight ban. Approximately 100 specialists are now working in continuous shifts toward a planned reopening the night of March 23–24.

Runway Resurfacing: Scale of the Work

The numbers are striking. Some 33,000 tonnes of asphalt — roughly three times the mass of the Eiffel Tower — must be moved across 76,000 square metres of active airside pavement. That’s the footprint of ten football pitches situated a few hundred metres from three concurrently operating runways.

Specialized milling machines are stripping the wearing course and binder course from the runway’s 4,000-by-60-metre surface, the airport’s longest and widest. Fresh high-durability asphalt is being applied in multiple lifts to meet the friction, evenness, and load-bearing tolerances required for wide-body aircraft operations. The surface last received a full overhaul in 2015; the new pavement is expected to last through approximately 2037.

FOD Risk at the Construction Boundary

Moving 33,000 tonnes of material through an active airside environment is not solely a civil engineering challenge — it is a sustained FOD containment operation running in parallel with live flight activity on adjacent runways.

More than 50 semi-trailers are supplying asphalt from surrounding mixing plants during peak paving windows. Any fragment shed from a loaded truck — a stone, a bolt, a piece of loose asphalt — that migrates onto an active taxiway represents a potential engine ingestion or tire strike event. Fraport’s FOD control program, which governs all construction activity in Frankfurt’s maneuvering areas, requires construction site managers to ensure no debris reaches operational surfaces. Under German aviation licensing law, vehicles posing a FOD risk can be denied airside access until the hazard is resolved.

Fraport is also implementing an on-site recycling operation for the first time. Around 12,000 tonnes of milled asphalt — up to 50 percent of removed material — is being transported to CargoCity South within the airport perimeter, crushed, and blended with virgin aggregate at a plant in nearby Kelsterbach before returning to the runway. The approach limits material handling to a defined airside zone and reduces the truck movements that would otherwise transit the airport access roads.

Electrical Upgrades Run Concurrently

Fraport is using the full closure to replace 450 in-pavement runway lighting units with LED technology. Teams installed more than 80 kilometres of underground cabling beneath the runway in the months prior to the closure. The LED conversion offers higher light output and longer service life compared to the existing halogen system — reducing the likelihood of unscheduled airside maintenance interruptions after the runway reopens.

Three-Runway Operations

With 25C/07C offline, Frankfurt’s three remaining runways — the northern runway (07L/25R), the southern runway (07R/25L), and Runway 18 West — are handling all traffic. The reduction in hourly capacity requires precise coordination with DFS Deutsche Flugsicherung, Germany’s air navigation service provider.

Airlines have been asked to maintain strict slot adherence. Irregular timings risk pushing aircraft ground movements closer to active construction zones. Frankfurt’s standard noise abatement rotation — which gives communities near specific runways quiet windows during off-peak night hours — has also been suspended for the duration of the project, as every available runway capacity is needed to prevent airside congestion.

Fraport says the schedule remains weather-dependent: asphalt paving cannot meet quality standards during frost or heavy rain, and buffer time has been factored in for potential delays.

Frankfurt served approximately 63.2 million passengers in 2025. The 2026 overhaul is part of a routine ten-year maintenance cycle, but its scale — and the proximity of heavy construction traffic to live operations — makes FOD discipline a critical variable in the project’s safe execution.
