| 摘要: | 隨著都市發展密度增高，造成地表不透水表面增加，雨水無法自然入滲與貯留，對於生態系統、水資源管理、都市微氣候都造成了無可忽視的衝擊，因此內政部建築研究所將透水鋪面納入綠建材標章制度裡，讓人們開始思考如何避免因交通或建築開發而造成自然環境的種種衝擊，尤其是水資源的相關議題，透水材料的觀念因應而生。
鋪面面層及基底層之透水材包含植草磚、連鎖磚、透水磚、透水性混凝土、砌石和多孔隙瀝青混凝土等，材料來源都是回收再生粒料，此外，多孔隙瀝青混凝土鋪面和透水混凝土鋪面可供需較高承載力之路面使用。
鋪面工程分為柔性路面與剛性路面，由於柔性鋪面行車舒適度佳，因此較常見的道路鋪面是柔性路面。多孔隙瀝青混凝土是柔性鋪面，其表面粗糙，提供足夠摩擦阻力，提升安全性等特性。
本研究藉由改變鋪設道路的材料，從密級配瀝青混凝土轉變為多孔隙瀝青混凝土的道路，希望能改善交通運輸行車安全、解決雨水資源流失、環境生態破壞及熱島效應日益擴張之問題。
參考歐美各國及日本所研究鋪設推廣的多孔瀝青混凝土，並在實驗室內研擬自製道路試體的透水性與抗壓強度，求得之結果，說明鋪設多孔瀝青混凝土透水鋪面於道路上的各項效益。藉此研究成果，能提供工程界規劃設計之參考。
With the increase of urban development density, resulting in surface impermeable surface increase, the rain can not be natural infiltration and storage, for ecosystems, water resources management, urban micro-climate has caused no significant impact, so the Ministry of Interior Building Research Institute will be permeable Pavement into the green building blocks system, so that people began to think about how to avoid the development of traffic or construction caused by the impact of the natural environment, especially water-related issues, the concept of water permeable materials born.
The permeable material of the pavement and the basement layer includes grass bricks, chain bricks, permeable bricks, permeable concrete, masonry and porous asphalt concrete. The material sources are recycled pellets. In addition, porous asphalt concrete pavement and pervious concrete Pavement for the use of high bearing capacity of the road.
Pavement works are divided into flexible pavement and rigid pavement. Because of the comfort of flexible pavement, the more common road pavement is flexible pavement. Porous asphalt concrete is a flexible pavement, its surface rough, to provide adequate friction resistance, enhance safety and other characteristics.
In this study, by changing the laying of road materials, from the dense asphalt concrete into porous asphalt concrete road, will be able to improve traffic safety, to solve the loss of rainwater resources.
Environmental ecological damage and heat island effect of the growing expansion of the problem Europe and the United States and Japan to study the laying of the promotion of porous asphalt concrete, and in the laboratory to study the porous asphalt concrete permeability and compressive strength, the results obtained, the laying of porous asphalt concrete on the road of the various benefits. I hope this research results, can provide engineering planning and design reference. |
