本研究旨在結合循環經濟材料與低碳技術，探討溫拌橡膠瀝青混凝土搭配平衡式配比設計的應用成效。研究中採用發泡瀝青技術製備溫拌橡膠瀝青，並進行多項試驗以評估其性能表現，包括抗開裂能力測試、抗車轍能力分析等及實地取樣異味測試。試驗結果顯示，本設計方案不僅能符合交通荷重需求，抗開裂指數亦遠高於國外之建議值。且溫拌技術成功降低橡膠瀝青帶來的異味問題，並證實在降低拌合溫度10至25°C的條件下仍保有良好的壓實性。本研究同時估算了使用廢輪胎橡膠粉的環境效益，顯示此作法能有效減少二氧化碳排放，達到節能減碳目標。 本研究建議未來可進一步探索其他溫拌技術，如有機添加料及化學添加料於實務應用上的效益，並引進Superpave或平衡式配比設計法，以因應交通量與交通工具日新月異的變化。另建議修訂國內路面工程驗收標準，將抗開裂及抗車轍能力納入考量，並制定完善的溫拌瀝青施工規範，以促進該技術在實務中的推廣與應用。 ;This study aims to integrate circular economy materials and low-carbon technologies to evaluate the application effectiveness of warm mix rubber asphalt concrete combined with balanced mix design. Foamed asphalt technology was adopted to produce warm mix rubber asphalt, and various tests were conducted to assess its performance, including cracking resistance tests, rutting resistance analysis, and on-site odor sampling tests. The results indicate that this design not only meets traffic load requirements but also achieves a cracking resistance index significantly higher than international recommendations. Additionally, the warm mix technology effectively reduces the odor issues associated with rubber asphalt and demonstrates excellent compaction performance under reduced mixing temperatures of 10 to 25°C. The study also estimated the environmental benefits of using recycled tire rubber powder, showing that this approach effectively reduces carbon dioxide emissions and achieves energy-saving and carbon reduction goals. This study recommends further exploration of other warm mix technologies, such as organic additives and chemical additives, to evaluate their practical benefits. It also suggests adopting Superpave or balanced mix design methods to address the evolving demands of increasing traffic volumes and modern transportation. Furthermore, it advocates revising the acceptance standards for domestic pavement engineering to include performance evaluations of cracking and rutting resistance. Establishing comprehensive construction specifications for warm mix asphalt is also recommended to promote the application and adoption of this technology in practical scenarios.
