| dc.description.abstract | 臺灣隨著經濟起飛，公共建設及民間工程蓬勃發展，導致天然資源日漸枯竭，然道路經新工或整修後衍生出之瀝青刨除料已面臨過剩及囤積問題。國內相關施工綱要規範訂定道路刨除料添加量上限為40%，額外之60%僅能以囤積作為處理方式，日積月累下來造成空間成本上升及再利用率低落之後果。目前臺灣大多民生管線皆埋設於道路底下，時常為因應民眾所需則必須進行道路開挖，然為配合開放通車時間，導致施工品質及養護品質參差不齊，進而衍生道路不平整及破壞等現象。本研究以國外冷拌再生技術結合國內道路底層相關施工規範進行配合設計，並進行現地驗證。為考量臺灣之材料特性，採3%水泥、2%發泡瀝青作為膠結材料。經90天齡期檢測後，整體道路水準仍維持於良好狀態，其中發泡瀝青混凝土(Cold Mix Recycled Asphalt Concrete, CMRA)之抗車轍能力優於熱拌瀝青混凝土(Hot Mix Asphalt Concrete, HMA)；於鋪面結構強度發泡瀝青混凝土之結構係數為0.41與熱拌瀝青混凝土結構係數0.44有相似之材料強度。然發泡瀝青混凝土鋪築後經滾壓已具有足夠之承載能力，與傳統工法相較下可減少約2小時施工時程。在成本分析上，發泡瀝青混凝土之成本較熱拌瀝青混凝土及控制性低強度混凝土低廉。綜合以上所述，發泡冷拌瀝青穩定處理技術係可運用於臺灣鋪面作為回填材料，值得近一步研究與推廣。 | zh_TW |
| dc.description.abstract | Taiwan pipelines for gas and daily needs are buried on the road and need a routine maintenance. Moreover, pipeline maintenance project also need to do in the short time due to traffic opening to avoid the rush hour and resulting in low construction and maintenance quality, uneven surface and premature damage. In recent years, Taiwan has been facing the lack of natural resources and accumulation of disposal material especially for Recliamed Asphalt Pavement(RAP). Therefore, excavation process due to pipeline maintenance become one of the contributor of the disposal material. According to the construction regulations, Taiwan promotes the using of recycling material, with the maximum limit of road excavation the recycling is 40%. However, the 60% rest accumulate the waste material and use many spaces for storing the waste material as the consequences of the low utilization rate. To solve those problems, this study used recycling asphalt, 3% cement, and 2% foam asphalt cementing materials, which focus on foreign cold mix recycled technology combined with Taiwan road construction specifications related to the underlying design procedure. The result shows after the 90th day test, the overall road level is still in good condition, and the anti - rutting ability of Cold Mix Recycled Asphalt Concrete (CMRA) is better than Hot Mix Asphalt Concrete (HMA). The structural coefficient of foamed recycled asphalt concrete with pavement strength shows 0.41, with similar material strength with HMA (0.44). However, the foamed asphalt concrete paving has been sufficient to carry the capacity after compaction compared with the traditional method, reduce the construction time of about 2 hours and has lower construction cost compared to HMA and controlled low strength concrete as the recent backfilling material. As mentioned above, the foam asphalt technology could be used as backfill material in Taiwan pavement and worth for the future study. | en_US |
