透水鋪面因為表層設計及底層材料變化，而導致入滲率不同。本研究利用南華大學透水舖面試驗場進行入滲濾量測試驗，試驗設備包括ASTM C1701規範之單筒試驗及ASTM D3385雙筒試驗，試驗鋪面包括碎石、JW路面(JWR)、JW停車鋪面(JWP)、植草磚、水泥連鎖磚五種透水鋪面，並以設計水泥連鎖磚底層材料分別為碎石(PICP-G)及碎石混合土壤(PICP-S)之試驗。表面滲透率量測設備比較結果，單筒試驗滲透率較雙筒試驗為大，係因為單筒試驗滲透至地下的水會往外側擴散，造成量測結果過大；鋪面透水性比較結果，由大至小分別為碎石、JWR、JWP、植草磚及水泥連鎖磚；底層材料影響結果，PICP-G透水性大於PICP-S，研究結果可作為設計者使用。 Permeable pavement has different water infiltration rate due to surface design and changes in the underlying material. This study used the Nanhua University permeable pavement test site to carry out the infiltration rate test. Test equipment includes the single cylinder test based on American Society for Testing and Materials (ASTM) C1701 and double cylinder test (ASTM D3385). Test pavement includes five kinds of pavements, which are gravel, JW pavement (JWR) and JW parking pavement (JWP), Concrete Grass Pavements (CGP), Permeable interlocking concrete pavement (PICP). PCIP also set up two kinds of underlying material, including gravel (PICP-G) and gravel mixed soil (PICP-S), so as to obtain the influence of underlying material on the infiltration rate. Experimental results showed that the permeability of the single-tube test is larger than that of the double-tube test. Water that penetrates into the ground by the single-tube test will spread to the outside, causing the measurement result to be too large. Infiltration rates from big to small are gravel>JWR> JWP>CGP>PCIP. Bottom material impact results is permeability of PPIC-G is greater than PPIC-S.
