摘要:	因應全球氣候變遷，為解決暴雨造成排水系統負擔，透水性鋪面能做為一舒緩之解決方案，但目前相關研究成果多建議將透水性鋪面應用於輕交通量區域，尚未廣泛應用於一般交通量之市區道路；且目前國內對於透水性鋪面底層材料尚未有一完整之規範準則。因此，研究首先探討混凝土再生粒料應用於透水性鋪面之特性；接著以再生材料分別應用於碎石級配與透水混凝土兩種形式來評估其成效，以探討再生材料運用於透水性鋪面底層之適用性，本研究欲提供一較佳之建議配比，期滿足道路工程承載力需求，並達到透水性鋪面透保水之效益。研究結果顯示，混凝土再生粒料使用於C-40碎石級配區間其CBR值均能滿足現行施工綱要規範第02726章級配粒料底層對一般碎石級配底層所建議之80以上，而滲透係數亦能滿足日本透水鋪裝所建議之10-3 cm/sec以上，經由選擇圖說可找出滿足透水性鋪面底層需求之設計乾單位重。而研究製作再生透水混凝土之單軸抗壓強度為7.4 kgf/cm2(105.7 psi) ~ 82.1 kgf/cm2(1172.8 psi)，惟水泥粒料比例在1:12之組別已無法滿足施工綱要規範第02794章透水性鋪面透水混凝土之要求，亦無法滿足交通部路工程施工規範中對水泥處理粒狀土壤之規定，故水泥粒料比例較低時在選用上應格外注意。最後本研究依研究之過程與試驗成果，對施工綱要規範第02794章進行探討並提出修改建議，使規範更趨完善，便於工程界使用參考。 In response to global climate change,to address the burden of the drainage system caused by heavy rains,permeable pavement do for a Soothing Solutions,but related research proposed permeable pavement used in multi-light traffic areas,not yet widely used in general traffic of urban roads and is currently base course of permeable pavement material for yet one full of normative guidelines. Therefore, the study first discusses recycled concrete aggregate used in permeable pavement characteristics Recycled materials were used followed by graded gravel and permeable concrete to assess its effectiveness in two forms,recycled materials used to explore the suitability of the base course in permeable pavement,this study is to provide a better proportionality of the proposal,to meet the demand of bearing capacity in road works and achieve the effectiveness of water contained and permeability in permeable pavement. The results showed that use of recycled aggregate concrete at C-40 graded gravel CBR value range can meet its current construction specification for 02726(graded aggregates graded gravel base)the general base course the recommended 80 or more,while permeability coefficient and also meet Japanese permeable paving the recommended 10-3 cm/sec or more,by selector drawings can be find the designed dry unit weight to meet the demand of the base course of permeable pavement.The study of the production of recycled uniaxial compressive strength of porous concrete is 7.4 kgf/cm2 (105.7 psi) ~ 82.1 kgf/cm2 (1172.8 psi),but the proportion of cement aggregates 1:12's group has been unable to meet the construction specification chapter 02794 (permeable pavement) permeable concrete requirements,they can not meet the Ministry of Transportation road construction specifications for cement treated granular soil condition,the lower the proportion of cement aggregates should pay particular attention in the selection. Finally,according to the study of the process and test results,explore and recommend changes for construction specifications chapter 02794,to make specification more perfect, easy to use engineering reference.
