The build up of rubber particle leads to reduced Runway friction values. The ICAO and FAA Advisory Circular 1520-12 provides detailed information and advice in regard to this problem. Friction Values must be carefully monitored and maintained to ensure that aircraft braking action stays within the ICAO and FAA safety parameters.

Runway downtime results in unnaceptable disruption to travellers and will also be the cause of significant loss of revenue to airport operators.
