Recommendation 3.2.2 - An appropriate program should be in place to maintain the runway surface friction characteristics by removal of contaminants.

Maintenance

In addition areas of the runway surface will wear down over time, depending on use, and this needs to be monitored by the airport operator. A smooth or **rubber contaminated surface** provides less friction than a textured one. Surface assessments or friction readings should be undertaken at adequate intervals to ensure that the runway surface remains suitable for continued operation. This may ultimately lead to runway resurfacing but improvements can be achieved also by improving the texture or removing for example rubber deposits that can build up over time. Should the condition deteriorate too far it may be necessary to advise aircraft operators that parts of the runway may have inadequate friction in certain conditions e.g. slippery when wet.

When constructing or resurfacing a runway the new surface should have an adequate texture to minimise the time window of exposure to slippery conditions after heavy rain showers.
