【摘要】 通过正交试验详细分析了粗型AC-16沥青混合料高温及水稳定性指标车辙动稳定度、冻融劈裂强度比与沥青混合料级配各筛孔通过百分率、油石比之间的影响关系。分析表明,对车辙动稳定度指标影响最为显著的因素为油石比;对冻融劈裂强度比指标影响最为显著的因素为4.75 mm筛孔通过百分率。更多还原

【Abstract】 The influence relation of the passing percentage of each mesh to DS and TSR which are indexes of high temperature perfomance and water stability of coarse AC-16 asphalt mixture through ortho-gonal test are analyzed.It shows that the most remarkable factor to DS is asphalt-aggregate ratio and to TSR is the passing percentage of 4.75 mm mesh.更多还原
