Tyre/road noise is the main source of excessive noise from road traffic. This problem applies to both cement and asphalt pavements. This paper presents the results noisiness evaluation of exposed aggregate cement concrete (EACC) in comparison to portland cement concrete (PCC) textured by other methods and SMA asphalt pavement. Studies conducted in Poland, have shown that EACC8 is characterised by a similar noise level to wearing course made of SMA11. Macrotexture plays an important role in the tyre/road noise on EACC. In the case of passenger cars, the optimal solution is a pavement characterised by a macrotexture with the MPD value lower than 0.8 mm, while in the case of multi-axle heavy vehicles the MPD value should close to 1.2 mm. The EACC can be characterised by an acoustic heterogeneity and one of the reasons for this can be mistakes made at the stage of exposing the aggregate.

轮胎/道路噪音是道路交通过度噪音的主要来源。这个问题适用于水泥和沥青路面。本文介绍了外露骨料水泥混凝土 (EACC) 与通过其他方法织构的硅酸盐水泥混凝土 (PCC) 和 SMA 沥青路面的噪声评估结果。在波兰进行的研究表明，EACC8 的特点是噪音水平与由 SMA11 制成的磨损课程相似。宏观纹理在 EACC 上的轮胎/道路噪音中起着重要作用。在乘用车的情况下，最佳解决方案是具有宏观纹理特征的路面，MPD 值低于 0.8 mm，而在多轴重型车辆的情况下，MPD 值应接近 1.2 mm。
