Abstract
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.
Highlights
In recent years, concrete pavement has been encouraged to replace the asphalt pavements because of their advantages, such as easy maintenance, long service life, and durability [1]. e concrete pavement is completely nonflammable and nontoxic in the case of a fire accident in tunnels [2]
Domestic research on tunnel engineering mainly focuses on the structural design and construction technology
Previous research on the concrete pavement used in tunnels mainly focuses on the skid resistance, and relatively little attention has been paid to noise reduction for ensuring driving comfort [7]

Concrete pavement has been encouraged to replace the asphalt pavements because of their advantages, such as easy maintenance, long service life, and durability [1]. E concrete pavement is completely nonflammable and nontoxic in the case of a fire accident in tunnels [2]. Compared to asphalt pavement, it can reduce the electrical energy consumption because of its light surface [3]. E most problematic of which are the skid resistance and noise [4,5,6]. Domestic research on tunnel engineering mainly focuses on the structural design and construction technology. Previous research on the concrete pavement used in tunnels mainly focuses on the skid resistance, and relatively little attention has been paid to noise reduction for ensuring driving comfort [7]
