To establish evaluation criteria for the pavement skid resistance and noise level in tunnels pavements, the zoning and control standards for skid resistance and concrete pavement noise were examined. Transverse friction coefficient (TFC) test equipment and the on-board sound intensity (OBSI) method were used to evaluate the antisliding characteristics and noise levels of several tunnel pavements. The results indicated poor antisliding characteristics and noise levels in ordinary grooved cement concrete pavement, whereas new types of cement concrete pavements, such as exposed concrete pavements and polymer-modified cement concrete pavements, had good antisliding characteristics and achieved low noise levels. Combined with the cluster analysis method, a zoning method for the antisliding and noise level in concrete pavement is proposed. The antisliding characteristics and noise levels of the pavement are divided into three zones. To ensure safety and comfort during driving, the antisliding value (SFC) of the tunnel pavement should be more than 50, and the noise level should not exceed 105 dB. Finally, the correlation between the antisliding and noise levels for pavement was analyzed. The results indicated that the antiskiding value of pavement has a strong correlation to the noise level.

各种类型混凝土路面的防滑性能和噪声特性分析

为了建立隧道路面的防滑性能和噪声水平的评估标准,研究了防滑和混凝土路面噪声的分区和控制标准。横向摩擦系数(TFC)测试设备和车载声强(OBSI)方法用于评估几条隧道路面的抗滑特性和噪声水平。结果表明,普通带槽水泥混凝土路面的抗滑特性和噪声水平较差,而新型水泥混凝土路面,如裸露的混凝土路面和聚合物改性的水泥混凝土路面,具有良好的防滑特性,噪声水平较低。结合聚类分析方法,提出了一种混凝土路面防滑和噪声等级的分区方法。路面的防滑特性和噪声等级分为三个区域。为了确保行驶过程中的安全和舒适,隧道路面的防滑值(SFC)应该大于50,并且噪音水平不应超过105 dB。最后,分析了路面的防滑和噪声水平之间的相关性。结果表明,路面的防滑值与噪声水平有很强的相关性。
