缝隙透水型路面关键设计参数及透水功能研究

Research on Key Design Parameters and Permeability Functions of Permeable Interlocking Pavement

针对传统透水砖路面透水功能耐久性差、强度不足的缺陷,借鉴欧洲、北美的成功建设经验,结合国内建设条件,试验研究了缝隙透水型路面的关键设计参数、透水功能测试方法和耐久性。试验结果表明,缝隙透水型路面具有良好的透水功能和力学性能,缝隙率宜大于7.5%,采用ASTM C1787M方法测试透水系数是有效的。

Aiming at the defects of poor durability and insufficient strength of permeable functions of the traditional permeable brick pavement,referring the successful construction experience of Europe and North America and combining with the domestic construction conditions,the key design parameters,permeation function test methods and durability of permeable interlocking pavement are experimentally studied.The test result shows that the permeable interlocking pavement has the good permeable function and mechanical property.The gap rate should be larger than 7.5%.It is effective to test the permeation coefficients by ASTM C1781/1787M method.
