Abstract
Periodic rubber removal from runway pavement surface is necessary to k eep an airport runway safe for aircraft operations. However, due to th e complex relationship between pavement friction and aircraft skidding , there are no clear-cut decision rules as to when a rubber removal op eration should be performed. The question is what pavement friction st ate should be selected as the activation level for rubber removal. A s ubjective approach to examining the area distribution of frictional re sistance of runway pavement surface has been in use in Singapore airpo rts for the last 15 years. This paper describes the development of a d ecision analysis framework based on past experience of rubber removal operations at the airport. This was carried out with the aim of reduci ng the reliance on a few experienced maintenance staff for such an ope ration, and of improving the consistency and continuity of the rubber removal decision-making process. The decision framework includes a neu ral network decision model for rubber removal, and a prediction model to estimate the growth of affected pavement areas for planning purpose .
