Runway Friction Testing Services

Runway friction testing as a service covers the full survey cycle an airport operator needs without owning and maintaining the test equipment itself: scheduling the test window around runway availability, running the continuous friction measuring equipment over the wetted surface at the required test speed, correlating readings against the reference friction device standard the national authority specifies, and issuing a friction report that maps coefficient against runway distance with any sub-threshold sections called out.

ICAO Annex 14 Volume I sets both the minimum friction level a runway must maintain and the survey frequency logic tied to traffic volume and pavement age, and GACAR applies the same reference framework to licensed Saudi aerodromes. A friction survey that skips correlation against the specified reference device, or reports an average rather than a full distance profile, does not meet what most national authorities actually require for a compliance submission, which is why the reporting format matters as much as the raw measurement.

Saudi airports run a heavier maintenance case than the ICAO baseline assumes on two fronts: touchdown zone rubber buildup accumulates faster on high-movement runways, and airborne dust settling on the pavement between rainfall events changes the surface's baseline friction independent of rubber contamination, so a friction survey scheduled only on a fixed calendar interval can miss a fast-developing low-friction section between visits. A testing programme built around actual traffic volume and local dust conditions, rather than a generic interval, catches degradation earlier than the minimum-compliance schedule does.

NLS delivers runway friction testing services on a turnkey basis, calibrated equipment, trained operators, and a correlated report against ICAO and GACAR reference standards, scheduled around an airport's operational windows to minimise runway closure time. A project typically starts with runway length, pavement type, and current traffic volume, and NLS returns a testing scope and schedule with a USD quote. Rubber removal and resurfacing recommendations, where a survey flags a section below threshold, are scoped as a separate follow-on rather than bundled automatically into the testing service.
