The assessment of runway friction evolution plays a key role in a modern Airfield Pavement Management System as far as safe aircraft operations are concerned. Friction degradation models are usually developed by statistical regression of skid resistance measurements carried out over several years. In this study, an experimental analysis was carried out on a regional airport, in order to evaluate the longitudinal and crosswise variability of friction on the runway. Then, an innovative approach, set up by analyzing the lateral variability of friction on a runway, for the development of empirical friction deterioration models, has been proposed. According to this methodology, the surface wear, induced by aircrafts, has been related to equivalent coverages, which have been evaluated by using a damage equivalency criterion based on frictional energy dissipated by tyre-pavement tribological system. Preliminary results seem to indicate that the approach is effective in evaluating friction deterioration.

Abstract
The assessment of runway friction evolution plays a key role in a modern Airfield Pavement Management System as far as safe aircraft operations are concerned. Friction degradation models are usually developed by statistical regression of skid resistance measurements carried out over several years. In this study, an experimental analysis was carried out on a regional airport, in order to evaluate the longitudinal and crosswise variability of friction on the runway. Then, an innovative approach, set up by analyzing the lateral variability of friction on a runway, for the development of empirical friction deterioration models, has been proposed. According to this methodology, the surface wear, induced by aircrafts, has been related to equivalent coverages, which have been evaluated by using a damage equivalency criterion based on frictional energy dissipated by tyre-pavement tribological system. Preliminary results seem to indicate that the approach is effective in evaluating friction deterioration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
