| Summary: | Skid resistance or friction on airport pavement plays an essential role in runway safety to ensure safe stopping
distance. It also provides safety margins during take off and landing of aircraft especially in directional control by
reducing the occurrence of overrun and veer-off incidents. The friction between pavement and tire is related to
multiple factors such as pavement surface characteristics (microtexture and macrotexture), material intruded
between tire and pavement surface (water, snow, and contaminants), tire conditions (types, wear, and inflation
pressure), and vehicle operating conditions (vehicle speed and whether the wheel is rolling or locked). Skid
incidents due to wet pavement surface at airport runway is a major concern especially in regions of wet-tropical
climate countries such as Malaysia. Thus, this study was undertaken to measure the potential of skid incident at airport
runway by collecting data on pavement surface characteristics. Field data collection on pavement surface
microtexture was conducted using the British Pendulum Tester at a local airport runway to obtain data for the
estimation of the skid number (SN). Due to constraints, pavement surface macrotexture test was unable to be
conducted at site. However, the pavement surface macrotexture was able to be estimated based on previous research.
The potential of the skid incident was estimated by calculating the SN using the aircraft’s touch down speed at the
airport runway, varies from 50 to 70 knots (57.5 – 80.6 mph or 92.6 – 129.6 km/h). The results of the estimation
indicated that the possibility of the skid incident occurrence was high. This study provides useful insights for airport
authority to investigate the potential of overrun and veer-off incidents of aircraft at the airport runway. |
