Abstract
The study aims to explore the feasibility of using anti-seepage layer asphalt concrete in highway drainage channels.An L9(33)orthogonal experimental scheme was designed to determine the optimal mix proportion of anti-seepage layer asphalt concrete by combining density,porosity,permeability coefficient,and slope flow tests.The experimental results indicate that density and porosity are mainly affected by the gradation index,permeability coefficient is mainly affected by the oil stone ratio and gradation coefficient,and slope flow value is mainly affected by the filler content and oil stone ratio.The optimal mix proportion of asphalt concrete for the anti-seepage layer is determined using the comprehensive balance method,with a filler content of 9%,an oil stone ratio of 7.0%,and a gradation index of 0.3.关键词
