　　It is known that the key function of pavement is to provide a safe and comfortable driving surface for moving transportation mode. Pavement with low skid resistance will cause high risk while the moving equipment decelerates and accelerates in a relatively high speed. This characteristic is even more important on airport pavement than on highway facilities. In this study, information was collected from airport authorities regarding their policy of skid evaluation. It is found that not much technique or knowledge of this field was introduced to Taiwan’s airport authorities.
　　The main objectives of this paper are to introduce the characteristics of pavement skid resistance and evaluation techniques, to analyze the threshold point of minimum skid requirement and the recommended measuring frequency, and to develop an user friendly program for analyzing the collected skid data. The standards of FAA and ICAO are used as the base to develop the program NTUSKID. Through field data collection using one of the major types of skid measuring equipment, Grip Tester, runway skid data of a specific airport were recorded and analyzed. It was concluded from the results of the program that NTUSKID can not only provide more efficient analysis than that from program developed by FAA, but also can specify the required maintenance for pavement section in order to promote its skid resistance ability.
