    Abstract: 由於營建資源日趨枯竭,再加上近年來政府對於維護環境生態的目標不斷要求,希望任何的廢棄物,都能藉由再生處理的過程,達成永續再利用目的。 本研究針對國內底碴資源處理廠處理過後之焚化爐底碴,分別進行長期物理性質分析,包括底碴比重、吸水率、單位重、磨損率、健性、氯離子含量、含泥量、毒物溶出試驗等,建立完整管制分析,以提供未來將底碴推動再利用有一完整背景資料說明。 根據研究成果發現,底碴對於取代瀝青混凝土細粒料是一可行的再利用方法,惟對於底碴經由SGC試驗發現其並不如一般天然粒料來的堅硬,試驗中發現底碴目前最佳的替代量約在30%以下,替代過多容易使整體瀝青混凝土發生級配降格情形因而造成結構強度變差。本研究也針對水洗過後底碴進行水泥混凝土摻配試拌,水洗過後的底碴已可完全解決以往底碴無法凝結的問題,並且氯離子濃度降低已可應用在一般附屬結構物中;另外使用底碴製作透水混凝土,不但達到綠建築九大指標中廢棄物減量指標,更符合了基地保水的指標。 本研究將試驗室所得成果,實際進行試鋪,並且藉由多項道路性能檢測,與實驗室成果進行比對,證明了底碴在道路工程上使用的可行性,最後再藉由成本分析及規範的擬定,提供未來相關使用參考。 As a result of the construction of resources going to exhausted and the purpose which requested by government, we hope to reach the objective of sustainable reuse by deal with discard materials in relive course. This thesis is to establish the control analysis which is aimed at the incinerate bottom trash deal with by factory of handle with resources. In order to provide the motion of bottom trash reuse in the future, this incinerate bottom trash was proceed physics analysis over a long period of time, including bottom trash specific weight, rate of absorptive, unit weight, rate of abrasion, content of cl-, content of mud, and TCLP. According to the result of research, they find it was a feasible reuse way to replace the bottom trash to fine granule material. In addition to find that the bottom trash was not harder than natural granule material by SGC test. As a result of the test, it can discover the best rate of replace is almost below or under 30%. If it replaces too many rates, it will make asphalt concrete to occur the grade degrades, and to cause the structure strength become weak. This study also aimed at precede concrete match mixed test by using bottom trash after washed. The bottom trash after washed not only can solve the problem which bottom trash can’t congeal, but also can reduce the concentration of cl-. In addition, the permeable concrete make by bottom trash not only reach the index of discard reduce in landscape engineering nine index, but also fill the bill of base of operations keep water index. The result of this study prove the bottom trash can workable used in pavement engineering by proceed the test build and many laboratory test. Eventually, it can provide user to refer to the cost analysis and draw up standard.
