摘要:	臺灣桃園國際機場北場05/23跑道自民國六十八年啟用，已達二十八年，南場06/24跑道自民國七十三年啟用亦達二十三年，因剛性鋪面已屆使用年限，需進行重新整建。而機場剛性道面表面因環境侵蝕、航空器反覆荷重影響，造成跑道表面老化，進而使機場管理單位面臨養護之問題如下： •已鋸縫之排水刮槽是否適合再做鋪面刨磨？ •跑道作刨磨對風化之鋪面是否造成更嚴重損害？ •如何解決跑道鋪面抗滑係數部分無法達到標準值？ •微觀紋理與巨觀紋理對摩擦之改善方法？高速粒子衝擊法為利用鋼珠衝擊混凝土及剛材表面的一種節省成本和環保的方法。本工法具有節省勞動成本和時間的優點。不同的結構物表面去除率，可透過改變衝擊能量，衝擊流動比率和機器行走速度來決定。當完成結構物表面清潔同時，亦研磨出新的表層。而Blastrac的軸心使用高性能離心輪軸系統，藉由離心拋射鋼珠撞擊混凝土表面，再由集塵器將打碎的橡膠、灰塵和表面帶著污染物的鋼珠回彈進入分離器。本研究介紹臺灣桃園國際機場採用高速粒子衝擊法清除胎屑，並於工法實施前後進行鋪面抗滑係數檢測，研究結果發現高速粒子衝擊法與高壓水刀法比較結果，高速粒子衝擊法可有效提升鋪面抗滑值。 Taiwan Taoyuan Int’l Airport has two independent-parallel runways – 05/23 at the north side that opened at 1979 experienced 28 years usage, and 06/24 at the south side that opened at 1984 experienced 23 years usage. Since the usage of both runways is getting on for the designed life, the reconstructions of both runways are earnestly needed. The aging of the rigid pavement at the airport is getting severe by weathering and cyclic loading from the traffic. There are several challenges that the maintenance department going to deal with: Is it appropriate to grind the surface of grooved runway? Will grinding cause more severe damage to the aged pavement? While part of runway’s friction value cannot meet the requirement, how to deal with? How the micro and macro texture affect the surface friction performance? Shot-blast is an economical and green method of surface treatment for concrete and steel.The work efficiency can be changed through the adjustment of impact energy, impact flow rate and the moving speed of the machine. This method can make a new surface of the structure while cleansing. Blastrac shot blasting systems use a high performance centrifugal wheel for propelling blast media at a high velocity, in a controlled pattern and direction. Metal abrasive, thrown by the rapidly rotating blast wheel, is accelerated towards the surface being prepared. The media strikes the surface and rebounds along with removed contaminants into a recovery chamber (separator). The dust collector removes pulverized abrasive, dust, and contaminants. Very little abrasive is lost and the usable media is returned to the storage hopper for recirculation by the blast wheel. This study introduces the result of rubber remove of runway with shot-blast method at Taiwan Taoyuan Int’l Airport. It is revealed that the shot-blast method can more effectively improve the friction characteristics of runway than other methods.
