本計畫執行期間自民國100年3月起至100年12月底止。 主要目標為推動底渣產品成為公共工程合格再生粒料。辦理試辦道路土壤及地下水環境監測計畫，以驗證環境安全性。同時，辦理底渣再利用產品工程性質抽樣調查，以提出施工綱要規範修正建議。 計畫期間協助辦理縣市政府底渣再利用補助款審查及底渣產品妥善再利用流向查核，並協助飛灰再利用示範驗證計畫審查會議等相關行政作業，藉以提高行政品質及效率。 底渣使用於道路試辦計畫，由交通部(公路總局)及內政部(營建署)分別提出3處試辦路段。本年度有2處試辦道路已完工。交通部公路總局以底渣與水泥混拌成多功能再生混凝土作為道路底層路床，營建署採用40%底渣與60%天然級配混拌作為道路底層級配，工程性質均符合道路施工綱要規範規定。在環境安全性驗證方面，完工後3~6個月內，土壤及地下水之重金屬濃度均無明顯變化，土壤戴奧辛亦同，初步推論無環境安全性疑慮。惟底渣使用於道路之長期溶出行為，仍應持續辦理環境監測予以驗證。 在底渣產品工程性質抽樣調查方面，執行包括CLSM、MRC、高壓混凝土磚及道路底層級配等產品抽樣調查，材料工程試驗結果均符合施工規範。此外，本計畫並就底渣納入施工綱要規範，提出4相關篇章之修正建議。

The Project was implemented over the period from March 24, 2011 to December 31, 2011. The main objective was the promotion of bottom ash products to become qualified recycled aggregates in public construction works. In order to verify the environmental safety of bottom ash used in road construction pilot program, we conducted soil and groundwater environmental monitoring plan. Secondly, we conducted the engineering properties survey of reused bottom ash products to regulate proposed amendments for “outline of specifications for public works construction”. Furthermore, the project assisted with bottom ash reuse subsidy review of county and city governments , and helped hold the review meeting for verification plan of fly ash reuse. Besides, the project also helped deal with the related administrative operations in order to improve the quality and efficiency. Bottom ash used in road construction pilot program by the Ministry of the Interior (MOI) and the Ministry of transportation and communications (MOTC) put forward three pilot sections, respectively. There were two pilot road have been completed in 2011. The MOTC used bottom ash mixed with cement into a multifunctional regeneration concrete (MRC) as road base, and the MOI mixed 40% bottom ash and 60% natural aggregates as the road base material. Both pilot projects were in line with the engineering properties of outline specifications requirements. Verification of environmental security, after the completion of 3 to 6 months, the soil and groundwater concentrations of heavy metals had no significant change, and the dioxin in soil likewise. Therefore, the results suggested that there were no environmental safety concerns. However, for the long-term dissolution behavior of bottom ash used in road, environmental monitoring should be continued for verification. Regarding engineering properties survey of bottom ash products, the implementation included CLSM, MRC, high-pressure concrete blocks and road base aggregates engineering property test, and all the samples tested were in line with the construction specifications. In addition, the project proposed amendments to the outline of specifications for public works construction in 4 bottom ash relevant chapters.
