| 摘要: | 本研究旨在評估瀝青混凝土挖（刨）除料（Reclaimed Asphalt Pavement, 簡稱RAP）經過添加水泥後，應用於道路基層的可行性與實際效益。近年來，道路養護工程中刨除的大量瀝青廢料若未妥善處理，不僅造成資源浪費，也帶來環境污染問題。因此，本研究以環保永續及經濟效益為出發點，探討將RAP資源化再利用的可能性。研究以「秀朗橋車行地下引道路面維護工程」為實際案例，透過設計、施工與評估等完整程序，驗證此再生技術在實務上的應用成果，並藉由系統性分析，建立一套可參考的施工與評估流程，為未來相關工程提供實證依據。
本研究首先進行文獻探討，整理RAP材料的性質、再利用技術以及目前國內外相關施工規範與應用案例；接著依據現地條件進行道路基層鋪面厚度設計、RAP與水泥的配比設計與試驗，並建立生產與材料管理機制，確保再生材料品質與一致性。於施工階段，則從材料來源控制、施工計畫擬定到現場檢驗，進行完整的工程管理，並搭配各項材料與鋪面性能檢測，如壓實度、強度及穩定性等，作為後續成效分析之依據。研究過程亦記錄並分析施工中遇到的問題與因應對策，增進技術應用的可行性與調整空間。
最後，本研究針對實際工程完成後的鋪面表現進行成效評估，透過檢測數據分析再生基層在耐用性、承載力、環境適應性等方面的表現。研究結果顯示，RAP添加適當比例的水泥後，其力學性質可滿足基層結構需求，並具有良好的現地施工與鋪面穩定效果。相較於傳統基層材料，該再生工法除能有效降低材料成本、減少新料使用與廢料產生外，亦有助於提升整體施工效率與環保績效。本研究證實RAP加水泥再利用技術具備實用價值，建議可納入未來道路工程標準做法，並持續推動其在不同工程類型中的應用與技術優化。
;This study aims to evaluate the feasibility and practical effectiveness of using reclaimed asphalt pavement (RAP), treated with added cement, as a material for road base construction. In recent years, large amounts of asphalt waste generated from road maintenance projects have posed both resource management and environmental challenges if not properly reused. With a focus on environmental sustainability and economic benefits, this research explores the potential for recycling RAP materials. Using the “Xiulang Bridge Underpass Road Maintenance Project” as a case study, the research follows a comprehensive process—design, construction, and performance assessment—to validate the application of this recycling method in practice. Through systematic analysis, the study aims to establish a reference framework for similar future projects.
The research begins with a literature review, compiling information on the characteristics of RAP, relevant recycling technologies, and existing national and international construction specifications and case applications. Based on site-specific conditions, pavement thickness design and RAP-cement mix design are developed and tested. A production and materials management system is also established to ensure consistent quality of the recycled materials. During the construction phase, complete project management is implemented—from source material control and construction planning to on-site inspections—along with various tests on materials and pavement performance, including compaction, strength, and stability. The process also documents problems encountered and corresponding solutions, enhancing the feasibility and adaptability of the applied technology.
Finally, the study assesses the effectiveness of the pavement after completion by analyzing test data related to durability, load-bearing capacity, and environmental adaptability of the recycled base layer. The results demonstrate that RAP, when mixed with an appropriate amount of cement, meets structural requirements and shows strong performance in terms of in-situ construction and pavement stability. Compared to traditional base materials, this recycled method not only reduces material costs and the use of virgin resources but also minimizes waste and improves overall construction efficiency and environmental outcomes. The findings confirm the practical value of RAP-cement reuse technology and suggest its inclusion in future roadwork standards, while encouraging further application and technical improvement across various types of engineering projects. |
