摘要:	過去十年間，冷拌再生瀝青混凝土技術已廣泛應用於台灣路面的基底層中，隨時間推移，冷拌再生瀝青混凝土勢必會面臨需刨除重鋪的問題，屆時勢必會產生來源為冷拌再生瀝青混凝土之刨除料，而如何再利用冷拌再生瀝青混凝土刨除料將是台灣未來將會面臨之重要課題。在目前台灣使用的冷拌再生發泡瀝青混凝土和冷拌再生乳化瀝青混凝土中常使用水泥作為黏結劑或填充材料。與傳統再生瀝青混凝土相比，冷拌再生瀝青混凝土中通常含有較多的水泥水化物質，這些物質是否會影響混合料的成效一直是鋪面工程師與學者關注的重要課題，本研究將針對上述背景進行深入探討。本研究的研究目的是評估冷拌再生乳化瀝青混凝土刨除料(CE_RAP)和冷拌再生發泡瀝青混凝土刨除料(CF_RAP)運用到熱拌再生瀝青混凝土和冷拌再生瀝青混凝土之可行性。在熱拌再生瀝青混凝土配合設計部分將依照美國瀝青協會 AI MS-2規範進行，冷拌再生瀝青混凝土將依照台灣國土管理署相關規範進行。並且根據不同種類再生瀝青混凝土採用間接張力強度、浸水殘餘強度、穩定值、滯留強度、IDEAL-CT試驗評估添加不同RAP、CE_RAP和CF_RAP對冷拌再生瀝青混凝土和熱拌在生瀝青混凝土之成效影響，此外也採用單因子變異數分析(ANOVA)來檢驗不同材料間的差異。盡管隨著CE_RAP和CF_RAP添加量增加，瀝青混合料的間接張力強度、浸水殘餘強度和抗水份侵害能力會降低，但上述缺點可以隨著水泥添加量與瀝青添加量提升而改善。綜合本研究成果而言，CE_RAP與CF_RAP可以在熱拌再生瀝青混凝土和冷拌再生瀝青混凝土中進行二次再利用，但是否能進行更多重之重複使用仍須進一步探討及研究。;For the past decade, Cold-mix recycled asphalt concrete technology has been studied and utilized in subbase and base layers of Taiwan pavement. As expected, the Reclaimed Asphalt Pavement (RAP) of Cold-mix recycled asphalt concrete will be produced, and how to recycle the RAP of Cold-mix recycled asphalt concrete is another crucial issue for Taiwan. The cement is adopted by cold-mix recycled foam asphalt concrete and cold-mix recycled emulsion asphalt concrete. Compared with the traditional RAP, the RAP of cold-mix recycled asphalt concrete contains more cement hydration material, and whether the above material would influence the performance is always a concern by pavement engineers and scholars. The study was developed on the above background. The objectives of this study are to evaluate the feasibility of Cold Mix Emulsion Reclaimed Asphalt Pavement (CE_RAP) and Cold Mix Foam Reclaimed Asphalt Pavement (CF_RAP) into Hot mix recycled asphalt concrete and Cold-mix recycled asphalt concrete. The hot-mix recycled asphalt mixture design followed the Asphalt Institute MS-2, and the cold-mix recycled asphalt mixture design followed the National Land Management Agency, Taiwan Specifications. The indirect tensile strength, tensile remain ratio, and moisture sensitivity were adopted to evaluate the performance of Cold-mix recycled asphalt concrete and hot-mix recycled asphalt concrete with various RAP, CE_RAP, and CF_RAP additions. In addition, one way Variance of Analysis (ANOVA) was adopted to check the difference between different materials. Although the indirect tensile strength, tensile remain ratio, and moisture sensitivity of asphalt mixture would decrease via the addition of CE_RAP and CF_RAP additions increase, the above disadvantage could be improved with cement and asphalt content. Based on the results, CE_RAP and CF_RAP could be reused in hot-mix recycled asphalt concrete and cold-mix recycled asphalt concrete. It would be worthy of further study.
