| Abstract | In recent years, due to the global warming in Taiwan, extreme weather conditions have emerged and rainfall patterns have changed. As a result, the frequency of heavy rainfalls has increased. To address the frequent waterlogging and reduce the load on the drainage system, Taiwan has actively introduced porous materials into the pavement in recent years. We hope to improve traffic safety and water conservation by using porous materials. The gradations used in this study refer to FHWA and NCAT in Europe, the specifications of drainage pavement design in Japan and the grading rules of each state in North America. Using high-strength modified asphalt, the porous asphalt concrete specimens were prepared, and the water permeability test, porosity test And other tests, analysis of various gradation physical parameter correlation value chart and characteristics of the relationship between the map to assess the different levels of different countries with water-permeable asphalt concrete pervious to water. After gradation adjustment, the values of four parameters of porous asphalt concrete gradation, such as volume porosity, interconnected porosity, effective porosity ratio and permeability coefficient, have been significantly improved, which effectively improves the drainage effect and helps to understand the material properties and help the materials Design choice. |
