摘要:	隨著臺灣每年道路總長及面積逐年增加，鋪設及養護所需之瀝青混凝土使用量逐年增加，而熱拌再生瀝青混凝土在法規的限制下，瀝青刨除料添加上限為40%，剩餘之刨除料只能堆置於廠內，導致多年來各縣市之廠商陸續貯存之刨除料已達飽和，進而衍伸出相關環保的問題。本研究著重於「冷拌再生面層環保新型瀝青混凝土」，透過添加新型材料「水性光硬化型樹脂(環保藥劑)」與再生瀝青刨除粒料進行冷拌並冷鋪於面層，以拓展其去化途徑。首先本研究設計不同的粗、細RAP摻配比例，進行馬歇爾配比試驗以及滯留強度試驗，以決定用於試鋪工程之較適配比，再依據現有規範進行彙整，訂定該材料在生產階段、施工階段及成效追蹤階段，所建議的品質管理項目與現地試驗項目，後續透過試鋪工程以及相關的品質管理項目與現地試驗項目，對該材料的現地試鋪成效進行數據統計分析，提出可行性評估與建議。配比試驗結果顯示較適配比之穩定值可達8000(lbs)以上，超過工程會「02742章」中重級交通之1800(lbs)或交通部高速公路局北區養護工程分局「瀝青混凝土路面整修工程特訂條款」中4000(lbs)，而滯留強度約達73.2%。而成效追蹤試驗主要採用非破壞性檢測，自完工後為期6個月，該材料之路面服務能力在成效追蹤期間仍維持優秀水準。 ;As Taiwan’s total road length and area grow annually, the demand for asphalt concrete in paving and maintenance continues to rise. Due to regulatory limits, hot-mix recycled asphalt concrete can only incorporate up to 40% reclaimed asphalt pavement (RAP), leaving the surplus stockpiled at plants. Over time, these stockpiles have reached capacity, leading to environmental concerns. This study proposes an environmentally friendly cold-mix recycled asphalt concrete for surface layers, using water-based photo-curable resin and RAP aggregates. The mixture is cold-mixed and cold-laid, aiming to expand RAP reuse while reducing carbon emissions from heating. Different coarse and fine RAP ratios were tested through Marshall stability and retained strength evaluations to determine the optimal mix. Quality control and field testing procedures were established for production, construction, and performance monitoring stages. Field trial results showed a Marshall stability over 8000 lbs, exceeding the 1800 lbs and 4000 lbs standards for heavy traffic. The retained strength reached 73.2%. Performance was monitored using non-destructive testing (NDT) over six months, during which the pavement maintained great serviceability.
