摘要
结合隧道路面功能需求,对具有抗滑低噪声特性的纵向刻槽水泥混凝土路面的抗滑性和降噪性能展开研究。采用SAFEGATE摩擦系数测试车及SCRIM车对试验路纵向摩擦系数和横向摩擦系数进行测试研究,同时对噪声水平进行1/3频谱的频谱分析。结果表明:相对于横向刻槽水泥混凝土路面,纵向刻槽水泥混凝土路面具有优异的抗滑性及降噪能力。
Combined with tunnel pavement function requirement,research on skid resistance and noise reduction function of longitudinal grooving cement concrete pavement with skid resistance and noise reduction function is made.Testing research on longitudinal and transverse frictional coefficient of test road is made by adopting SAFEGATE frictional coefficient test car and SCRIM car,and meanwhile 1/3 spectrum analysis on noise level is made.The result shows that in comparison with transverse grooving cement concrete pavement,longitudinal grooving cement concrete pavement has excellent skid resistance and noise reduction function.
