摘要:	本研究針對溫拌瀝青混凝土(Warm Mix Asphalt, WMA) 進行成效評估，探討其應用於現地施工的可行性與效益。隨著氣候變遷對環境的影響日益嚴重，建築材料和施工技術的環保性變得愈發重要。本研究特別關注溫拌瀝青混凝土在減少碳排放和降低施工溫度方面的潛力，作為應對氣候變遷的有效策略之一。研究首先回顧了溫拌瀝青技術的發展歷史和現狀，並蒐集了各類添加劑的技術資料。實驗部分採用了三種不同的溫拌添加劑進行配合設計與試驗，通過穩定值試驗、滯留強度試驗、間接張力強度試驗、抗水份侵害試驗和漢堡車轍試驗等多項測試，對比分析了溫拌與熱拌瀝青混凝土的性能差異。結果顯示，溫拌瀝青混凝土在降低施工溫度和減少碳排放方面具顯著優勢，同時能夠保持與熱拌瀝青混凝土相當的機械性能。此外，本研究還進行了經濟效益分析，證實溫拌瀝青混凝土在降低能耗與成本方面具備良好的應用前景。綜合而言，溫拌瀝青混凝土不僅是提升施工效能和經濟效益的重要選擇，更是應對氣候變遷、實現可持續發展的重要途徑之一。;This study evaluates the effectiveness of Warm Mix Asphalt (WMA) and explores its feasibility and benefits in field applications. With the increasing impact of climate change on the environment, the sustainability of construction materials and techniques has become more important. This research particularly focuses on the potential of WMA to reduce carbon emissions and lower construction temperatures as an effective strategy to address climate change.The study begins with a review of the development history and current state of WMA technology, collecting technical data on various additives. The experimental part employs three different WMA additives for mix design and testing, including stability tests, retained strength tests, indirect tensile strength tests, moisture damage resistance tests, and Hamburg wheel-track tests. The performance differences between WMA and Hot Mix Asphalt (HMA) are compared and analyzed. Results show that WMA has significant advantages in reducing construction temperatures and carbon emissions, while maintaining mechanical performance comparable to HMA.Additionally, this study conducts an economic benefit analysis, confirming that WMA has promising application prospects in terms of energy consumption and cost reduction. Overall, WMA is not only a crucial choice for enhancing construction efficiency and economic benefits but also an important approach for addressing climate change and achieving sustainable development.
