Friction and skid resistance are critical safety parameters of airport pavements, particularly on runways, where braking performance directly affects aircraft landing and take-off safety. Friction testing is conducted regularly on runways in accordance with CAP683 – or specifically where
areas of contamination have been identified or following rubber removal – to identify low-friction areas where there is a risk of aircraft hydroplaning.
GripTester is a Continuous Friction Measurement Equipment (CFME) device that measures the friction coefficient (Grip Number) of the paved surface. GripTester is a three-wheel trailer with a single measurement wheel braked by 15%. The test is conducted on a 1mm film of water and typically at 65km/hr. GripTester surveys provide quantitative, repeatable, and comparable friction data, which forms an essential part of proactive airfield pavement safety monitoring and operational decision-making. Data from GripTester runs are used to:
- Verify compliance with ICAO Annex 14 and UK CAA CAP683 minimum friction standards
- Support runway condition assessments and maintenance planning
