摘要:	本研究探討瀝青混凝土挖(刨)除料進瀝青拌合廠破碎後，對瀝青混凝土挖(刨)除粒料分析相關試驗(含油量、篩分析、黏滯度)後，以黏滯度 100,000(poise)以上及黏滯度100,000(poise)以下做為分級之條件，再將此兩種再利用粒料分別以40%、60%、80%比例摻配天然碎石級配混合後，調配適當之篩分析配比，以模擬路基底層級配，透過夯實試驗及加州承載比 (CBR)試驗，探討不同黏滯度應用於不同比例之再利用粒料對於路基底層承載能力之影響，經試驗後發現黏滯度對於承載能力之影響不大，對於承載能力影響主要因素為瀝青混凝土挖(刨)除粒料摻配比例，且CBR 值與摻配比例成反比。另外，本論文也歸納整理出國內相關施工規範，並實際操作使用桃園循環經濟平台的最新資訊和功能，及桃園市政府目前已經施作相關工程案例，透過不同施工規範間之差異及本文中的相關數據與試驗過程中材料特性的了解，撰寫瀝青混凝土挖(刨)除粒料應用於路基底層之供料計畫書，以供後續相關工程單位應用時之參考，並期待本文可以提昇道路工程品質及促進基礎建設的永續發展。;Asphalt pavement mixed from recycled asphalt with varying viscosity lead to different impacts on the bearing capacity of its base course. The impact result is obtained by analyzing reclaimed asphalt by their oil content, screen analysis, and viscosity. A classification of asphalt according to their viscosity with a dividing line of 100,000 (poise) is performed. The two classes of recycled aggregate are then each blended with natural gravel grades at ratios of 40%, 60%, and 80%, respectively. Result from which is applied in the screen analysis to simulate the base course of multiple grades, and finally go through compaction and California Bearing Ratio(CBR)tests to achieve the final results. Results show that viscosity has little effect on the bearing capacity. The main factor affecting the bearing capacity is the ratio of recycled aggregate. Of which is inversely proportional to the CBR value. In addition, this thesis summarizes relevant domestic construction specifications, and uses the latest reports, construction specifications, services, and other information provided by the Taoyuan City Circular Economy Platform, as well as ongoing constructions executed by the current Taoyuan City Government, and differences in between, to provide a proposal detailing the supply for reclaimed asphalt for base course applications, in hopes to provide aid to future constructions and the sustainable development of infrastructure.
