Accumulation and excess rubber that come off from the tires of airplanes will actually lower the friction of runways, specially when wet. Instead of adding grip, having hundreds and thousands of flights add rubber onto rubber on the runway causes a polishing action, which removes the anti-skidding and resistance of runways. When a plane lands, the tires are not spinning. The time it takes for the tires to get up to speed is referred to as ‘spin up time’. During this time the tires are effectively dragging on the runway as well as being put under pressure by the weight of the airplane. This can be seen in the slight puff of smoke that comes from a landing aircraft’s tires as they first touch the runway surface. The friction built up causes the rubber to polymerize and harden to the runway surface. In the USA, the Federal Aviation Administration (FAA) specifies friction levels for safe operation of planes and measures friction coefficients for the evaluation of appropriate friction levels. Individual airports incorporate rubber removal into their maintenance schedules based on the number of take offs and landings that each airport experiences.
