在機場跑道鋪面之維護管理中，抗滑值為衡量鋪面服務安全績效的主要指標，良好的道面抗滑能力對於起降之飛機而言不僅可以增加煞停能力，更可協助飛機受側風影響或引擎故障時維持適當的方向控制；因此對於機場跑道抗滑值，應進行定期檢測與維護，俾使道面抗滑值得以維持在安全門檻值以上。而機場跑道抗滑值除影響飛機之起降行為外，對於其他操作行為亦影響甚鉅，故本研究主要以飛機取消起飛煞停之操作方式，研擬跑道摩擦係數門檻值。 本研究首先針對機師以問卷調查提供個人專業意見，結果顯示機師於操控飛機時，多受跑道抗滑值良寙影響，對於飛機於特殊情況下取消起飛而煞停之操作行為，皆認為鋪面所提供之煞停力對於飛機減速貢獻最大。另本研究以中正機場06/24跑道為模擬環境，經比較後以B747-400作為飛機取消起飛、緊急煞停之探討機型，最後利用能量轉換觀點推導跑道摩擦係數門檻值。

Skid resistance ability is one of the most important characteristics for performance of airport pavement safety. It not only affects the braking ability of aircrafts, hut also improves the controlling of aircrafts direction that is affected by crossing wind or engine failure. Therefore, a periodical measurement of runway friction resistance is rather important. The objective of this paper is to develop the appropriate threshold value for runway skid number from the most critical view point: aircraft takeoff abortion. Questionnaires collected from pilots indicated that the pavement skid num her has a great contribution to the aircraft braking ability, especially tinder the takeoff abortion situation. In this paper a Boeing 747-400 takeoff abortion process is simulated at the 06/24 runway of Chiang Kai-Shek International Airport, and the friction threshold value is derived by energy transmission theory.
