由於天然資源日趨枯竭，為了維護環境生態並確保人類社會經濟的永續發展，未來營建工程所使用之材料勢必朝節能化及再生化方向發展。經適當處理及品質管理後之再生材料，亦可應用視其特性於國內各項土木水利等工程建設，以達全面推動資源化之目的。 台灣地區經濟快速成長，對於道路運輸系統的需求與品質亦逐年提高，因此道路工程之料源需求量大幅增加，然台灣地區天然砂石料源開發已面臨短缺之瓶頸。為促進公共建設之興建能兼顧生態環境維護及自然資源永續利用，本研究特針對公共工程中的道路鋪面工程，分成四個階段，從資料收集到實驗室試驗，再經由現地鋪設與實際應用，最後進行再生材料的各項成效評估。從再生材料分類及處理技術進行成本分析，得以結合處理技術與市場經濟角度，並藉由瞭解再生材料之經濟及生態等效益，加速提昇國內資源回收再利用的比例，最後以實驗室中的配合設計案例探討再生材料於未來工程普遍應用的可行性。 Due to the gradually decreasing our natural resources, to protect the environment, and to ensure the sustainability of our society, the materials that would be used by construction engineering development in the future must be heading toward both energy saving and recycling aspects. Recycled materials, which had been properly treated and qualified, could be applied to various kinds of domestic civil engineering constructions, according to their characteristics, then we can achieve the purpose of fully driving the regeneration of waste materials. The need and quality demand of our transportation systems had increased year by year due to Taiwan’s rapid economic growth. Therefore, the demand of raw materials for pavement engineering increases enormously. Thus, the exploitation of natural sandstones as raw materials in Taiwan is facing the bottleneck of supply shortage. As to promote the construction of public facilities that could give consideration both on environmental protection and sustainable use of natural resources, this research aims at the pavement construction, and divides it into four phases. First from collecting data to laboratorial tests, then from on-site pavement to practical applications, and gradually we proceed various types of cost-effective evaluation of recycled materials. With the cost-benefit analysis of both the classification of recycled materials and treatment technologies, plus the understanding of the recycled materials’ economical and environmental benefits, we can speed up the raise of the proportion of reuse and recycle in our country. At last, we confer on laboratorial-designed cases with the possibility of general applications of recycled materials on future constructions.
