Component

The skid resistance of runway pavements plays an important role in aviation safety. It is also one of the indices that are used to establish the runway pavement maintenance schedule. The temperature is considered as an important factor that affects the friction value. However, the effects of temperature and how to correct the friction value by temperature are of little concern in skid resistance test specifications. The concept of modern pavement management is that preventive maintenance has higher efficient improvement than that of maintenance when the runway pavement conditions are reaching the critical values. Thus, to predict the skid resistance deterioration accurately is essential. In this study, friction data collected at Airport A in Taiwan are analyzed to determine the temperature effects. It is found that the GN values obtained with the device of Grip Tester decreases 0.005 when the air temperature increases per 1¢J. If the temperature variation exceeds 20¢J between two consecutive measurements, the variance would be large enough to influence the maintenance decisions. Using the value of -0.005 per 1¢ increase in temperature to correct the GN value can definitely provide a better picture of the actual condition of runway skid resistance capability. This method can also be applied to evaluate the results of runway maintenance such as rubber removal. However, the temperature correcting value should be identified for different friction measuring devices and airports.
