摘要:	國際機場為台灣對世界的重要門戶與橋樑，其鋪面建設成效攸關台灣與世界間之鏈結；為了更容易維護及修補機場，鋪面常會選擇瀝青混凝土材料進行鋪築，而瀝青混凝土係種感溫性材料受環境溫度影響甚大，需探討機場地區氣候變化對鋪面溫度影響，並建立鋪面溫度預測模式；本研究透過現地埋設溫度感測器蒐集機場鋪面溫度及鄰近氣象站之氣候資料，以逐步迴歸統計方式建立各季節鋪面溫度預測模式，最後探討其實際應用成效及分析該溫度預測模式與LTPP預測模式之差異。研究結果顯示，本研究建立之春季、夏季及秋季溫度預測模式實際應用時為高準確預測，冬季為優良預測；且實測應用時發現，鋪面升溫階段預測值與實測值吻合，但降溫階段則預測值較實測值低之情形，表示本研究建立預測模式較適合應用於該機場鋪面升溫階段，故建議後續研究可以考慮將鋪面熱量之因子納入鋪面溫度預測模式中，且可針對鋪面溫度對鋪面成效影響進行研究，建立各式鋪面成效預測模式提供工程界使用。;The international airport is an important hub between Taiwan and world,it’s the performance of their pavement construction of crucial to the linkage between Taiwan and the world.In this research,the pavement temperature and weather data were collected from weather stations and thermal couples in the field,iy also established the pavement temperature prediction model for each season by using stepwise regression analysis,by evaluate the performance of its application and analysed the differences of LTPP temperature prediction model.The results of this study showed that the temperature prediction models established were highly accurate in spring, summer and autumn were excellent in winter.In addition,it was found that the predicted values of the pavement at warning stage were matched with the measured values,but the predicted values of the cooling stage were lower than the measured values.So if the future studies could consider the pavement thermal conductivity into pavement temperature prediction model,also can explore the effect of pavement temperature on pavement performance,it would be helpful for application for the engineers and scholars.
