Road traffic noise is the most common source of environmental pollution in urban areas, and therefore, the study of noise mitigation actions is fundamental for urban planning. The use of low noise road surfaces is one of the most widespread intervention since it acts directly on the source of road traffic noise, represented by tyre/road interaction. In this work, the interaction between texture and tyre/road noise was studied from an experimental point of view, by comparing CPX and road texture measurements on rubberised and standard road surfaces. Tyre deformation was addressed by taking into account the indenter method proposed by Sandberg and Goubert in 2018. Regressions of CPX and enveloped road texture levels were performed separating rubberised from reference surfaces, and parallelism tests were performed on the slopes. Results show that the use of rubber influences the interaction of road texture and noise, especially at high frequencies.

道路交通噪声是城市地区最常见的环境污染源，因此，研究噪声缓解措施是城市规划的基础。使用低噪声路面是最广泛的干预措施之一，因为它直接作用于以轮胎/道路相互作用为代表的道路交通噪声源。在这项工作中，从实验的角度研究了纹理与轮胎/道路噪音之间的相互作用，方法是比较CPX和橡胶表面和标准道路表面上的道路纹理测量结果。通过考虑Sandberg和Goubert在2018年提出的压头方法解决了轮胎变形问题。CPX的回归和包围的路面纹理水平通过将橡胶表面与参考表面分离开来进行，并在坡度上进行了平行度测试。
