| 摘要: | 研究期間：10108~10207;In the past, the vast use of impermeable pavement design in Taiwan has made the land lost the function of maintaining moisture and infiltration. Urbanization that reduced the original natural land and replaced it by buildings and artificial pavement significantly reduce water infiltration. Typhoon or heavy rain that encountered seasonally also causes floods in some areas. Some researches indicated that reducing the urban impervious surface may reduce the impact of heat island effect. In recent years, Taiwan has been promoting green building and eco-city with Water Retention as one of the indicators, since then, the concept of Ecology and Water Retention started to be emphasized by the engineer. Foreign research mentioned that permeable pavement can increase the permeability of pavement, reduce surface run-off, and reduce heat island effect. There are few studies has been done for permeable pavement characteristic in Taiwan. The objectives of this paper is to study the void ratio, permeability coefficient, temperature behavior, infiltration, reduce run-off, water retention and other performance assessment analysis, and to discuss the functional properties of "high-performance permeable pavement". Laboratory experiment was used to study the void ratio, permeability coefficient, and cooling condition from the surface layer material. And actual cases were used to measure the actual pavement temperature changes, water retention, infiltration, and run-off. Finally, statistical analysis was used to evaluate the quantitative results. |
