    Abstract: 有鑑於台灣地區天然資源有限,政府遂於民國八十五年推動再生瀝青混擬土利用。但依行政院公共工程委員會所頒布的施工綱要規範,再生瀝青混凝土的瀝青刨除料添加量最高上限為百分之四十,而額外的百分之六十瀝青刨除料將無法使用於瀝青鋪面中。此外,各縣市政府近年來大力推動的路平專案,也使得瀝青鋪面經養護後所產生的瀝青刨除料持續增加,進而造成環境汙染。
    透過國外發泡瀝青技術做為穩定方式,本研究將瀝青刨除料應用於道路底層以評估回收刨除料輔以發泡技術之本土適用性。實驗結果顯示,瀝青刨除料經發泡瀝青穩定技術處理後不僅符合國內相關規範,且卵石當量值也優於天然碎石級配和瀝青處理底層。
    在生產過程中,熱拌工法的消耗能源碳排放量是生產冷拌的109.91倍,且每公噸熱拌瀝青的消耗能源成本也高達生產冷拌的55.32倍;從生產材料角度來看,熱拌工法使用材料的碳排放量相當於冷拌工法的1.26倍,且每公噸的材料成本也相當於冷拌工法的2.04倍。
    經實驗室所進行的成效試驗及效益試算,研究發現發泡瀝青穩定處理底層可應用於道路底層中,除可降低成本更可達碳足跡減量之效益。

    ;Due to limited natural resource in Taiwan, the reclaimed asphalt is, therefore, chosen as a raw material that the country could reuse in road pavement. Since 1996, the government of Taiwan has pursued a project of recycling reclaimed asphalt. However, according to The Chapter Outline Section, published by Public Construction Commission, Executive Yuan, it has a stipulation that the maximum quantity of reclaimed asphalt pavement (RAP) added is 40%, and thus the rest of the RAP cannot be used in the asphalt pavement. Besides this, the local governments have urged the Road-Smoothing Project actively. As a result, the project significantly increases the quantity of RAP after road maintenance, causing environmental pollution.
    Based on the foamed bitumen stabilization technique, this paper examines whether the recycled asphalt with the mixing of foam bitumen would be suitable and applicable in Taiwan by using RAP as the base layer of the pavement. The result of this study shows that, after foamed asphalt effectiveness test, RAP would not only meet the industry legislation in Taiwan, but also provide superior quality compared with bitumen treated base and natural aggregate. In terms of the production process, the carbon emission of hot mix asphalt (HMA) is 109.91 times greater than the carbon emission of cold mix asphalt (CMA). In addition, HMA energy cost per ton is up to 55.32 times higher than the cost of CMA. From a perspective of production material, the carbon emission of HMA material is also more than CMA materials by 26 percent. What is more, the cost of HMA material per ton is 2.04 times more than what CMA material costs.
    According to the effectiveness and efficiency test, which conducted by the laboratory where the researcher worked, the foamed asphalt base could be used in the base layer of the pavement to reduce the cost and the carbon emission.
