摘要:	本研究之目的，針對機場新增設W1、W2 二條可供F 類航機通行之滑行道，於新建道面上採用具有高耐久性、高抗車轍性且滿足機場道面抗滑性的石膠泥瀝青混凝土SMA，近期使用中之跑、滑(道)均有發生車轍及壓密沉陷之情事，而其發生原因是否因為航機起降與停等頻率過於頻繁，而或是航機於滑行道停等時間過久導致(SMA)面層因溫度過高而軟化等因素所致進行探討。首先對使用鋪築近一年之1/2”石膠泥瀝青混凝土進行鑽心取樣，經由試驗後之數據與原配合設計成果進行比對並判斷其材料之適用與耐用性。另沿用機場道面強化標之3/4”高黏滯度改質瀝青混凝土SMA 配合設計，依據該配合設計及規範進行廠拌及相關材料檢驗與試驗均符合該標規範要求；並針對1/2”改質Ⅲ與3/4”高黏滯度改質瀝青膠泥進行性能比較，經比較後其軟化點、黏度、滯留強度等3/4”高黏度改質瀝青優於1/2”改質Ⅲ瀝青。因原鋪面產生損壞而針對鋪築後缺失問題探討，探討缺失範圍及可能發生原因進而針對缺失進行改善措施，並將缺失部分刨除後重新鋪築材料是以比較後之3/4”高黏滯度改質瀝青混凝土為主，鋪築前埋設溫度感應器進行道面溫度檢測，以期後續暑假期間天候溫度是否造成石膠泥瀝青混凝土(SMA)損壞之成因。;This research will focus on Taoyuan International Airport added W1 and W2 two taxiways for F-class aircraft on Taoyuan International Airport, and to use the Stone Mastic Asphalt SMA with high durability, high rutting resistance and meet the anti-slip resistance of the airport road surface on the W1 and W2 taxiways, Slip (road) have the occurrence of ruts and pressure sink, and whether the cause of the occurrence is due to the aircraft take-off and landing and stop frequency is frequency, or It′s been too long to stop by (SMA) surface layer due to high temperature and softening and other factors caused by the discussion. First of all, the use of paving nearly 1/2" particle size Stone Mastic Asphalt drill-center sampling, through the test data and the original design results to compare and judge the application and durability of its materials. Another use of road surface on Taoyuan International Airport reinforcement mark 3/4" particle size high viscosity modified bitumen SMA cooperation design, according to the overall design and specifications of the factory mixing and related materials inspection and testing are in line with the standard requirements; With 3/4" particle size high viscosity modified asphalt gel performance comparison, after comparison of its softening point, viscosity, retention strength and other 3/4" particle size high viscosity modified asphalt better than 1/2" particle size modified III asphalt. Due to the damage caused by the original paving surface and for the lack of the problem of paving, to explore the missing range and possible reasons for the lack of improvement measures, and the missing part of the removal of the re-laying material is based on the comparison of 3/4" particle size high viscosity modified bitumen, pre-laying temperature sensor for road surface temperature detection, with a view to the subsequent summer period whether the temperature caused by the damage of Stone Mastic Asphalt (SMA).
