摘要
文中以PAC-13混合料为研究对象,采用玄武岩纤维对透水沥青路面的力学性能进行改良,并开展多种室内试验对其影响效果进行分析和评价。结果表明:通过析漏试验确定纤维改良PAC-13混合料的最佳油石比为4.6%;纤维的掺入提高了PAC-13混合料渗水的有效空隙率和渗水系数;推荐采用0.3%的玄武岩纤维掺量,使得PAC-13混合料达到较佳的排水功能和路用性能。
In this paper,the mechanical properties of PAC-13 mixture is studied and improved by the basalt fiber.Meanwhile,various laboratory tests are undertaken to analyze and evaluate its modified effect.The results show that the optimum asphalt aggregate ratio of fiber-modified PAC-13 mixture is 4.6%by the drain-down test.Blending of the fiber blending has improved the effective void ratio and water permeability of PAC-13 mixture.It is suggested to use 0.3%basal fiber content in the PAC-13 mixture to achieve better drainage and road performance.
