台灣面臨全球化之競爭,客、貨之運輸要求迅速、準時,故對航空運輸之需求與日俱增,國內目前共有18座民用機場,每日有無數之航機起降於跑道,如何確保機場跑道鋪面之抗滑值能維持在最佳狀況,以提供航機安全的起降,確保生命、財產之安全實為一重要之課題。鋪面之抗滑性能是由其粗質紋理(Macrotexture)及細質紋理(Microtexture)所提供,故二者之深度大小決定了鋪面抗滑性能之良窳,本研究以高雄國際機場09/27跑道為對象,藉由連續抗滑檢測儀器(CFME, Continuous Friction Measuring Equipment)Surface Friction Tester T-10及油脂塗佈法,檢測跑道鋪面之抗滑值及粗質紋理深度,進而探討跑道鋪面胎屑沈積之範圍、胎屑沈積之方向性、抗滑值隨航機起降架次及胎屑沈積之變化情形等,並且進行化學藥劑清洗法以及高速衝擊法清除跑道胎屑之有效性統計檢定分析。
由研究結果可獲知跑道胎屑沈積為降低高雄國際機場跑道抗滑值之主要原因之ㄧ且跑道之著陸區為主要胎屑沈積之區域,而胎屑之沈積是具有方向性,其類似於魚鱗狀似的一層、一層地順著起降方向覆蓋在鋪面的上方,本研究亦觀察出高雄國際機場平均每架次航機起降造成09跑道主要胎屑沈積區域之鋪面抗滑值降低約9E-06且在既有航次起降下,抗滑值平均每日下降約0.002。
本研究以油脂塗佈法檢驗出跑道之粗質紋理深度會隨累計時間之增加而下降,並由建立之抗滑值與粗質紋理深度間相互關係獲得R2值高達90%以上之迴歸曲線,另本研究採統計檢定方式得知在高雄國際機場以高速衝擊法清除跑道胎屑較化學藥劑法有效,而其合適之胎屑清除頻率為2.5個月。
Facing global competitions in Taiwan, it is requirement for passenger and cargo aircraft to be fast and on schedule, therefore the demand of air transportation is growing with each passing day. At present there are numerous aircrafts taking off and landing on runway within 18 civil airports nationwide in Taiwan. How to ensure the surface friction always sustains at the top condition, and provides aircrafts landing and taking off safely on runway which can assure safety of life and fortune are the major task for airport maintenance department. Offering the skid resistance of runway pavement, depths of macrotexture and microtexture decide good or bad performance of which .The study took the 09/27 Runway of Kaohsiung International Airport for example, using self-owned continuous friction measuring equipment (CFME)----Surface Friction Tester T-10 to inspect the friction of pavement of runway, with which to inquire into the scope and orientation tendency of rubber deposit of runway surface, and the change situation of friction value following by sortie of take-off and touchdown of aircraft and rubber deposit. Then carried on examining the change situation of friction value before and after clearing away the rubbers, following applying chemical agents and adopting high velocity impact removal.
Rubber deposits is the major factor to decrease friction of Kaohsiung international airport runway obtained by research result, and the touchdown area of runway is the major rubber deposits zone. However rubber deposits appear characteristic of different direction, which is similar to be fish scale shape flake by flake following aircraft taking off and landing direction and covering the top pavement. It is also observed by the study that an average of each aircraft landing and taking off causes decreasing 9E-06 of pavement friction on the major rubber deposits zone of 09 runway, besides friction averagely reduced about 0.002 under the number of usual flights landing and taking-off.
Taking the grease smear method, the study whereby surveyed that the depth of macrotexture reduces as time goes by, and to obtain more than 90% regression curve through establishing mutual relationship between friction and depths of macrotexture. On the other hand the study with statistical testing proves that adopting high velocity impact removal is more effective than applying chemical agents, which the adequate removal frequency is 2.5 months.
