Several parameters are monitored on roadways as skid resistance, surface roughness, macrotexture, and bearing capacity. These parameters have classification scales for evaluation, but not yet the noise level. A questionnaire survey was conducted within CEN, which showed that the CPX method is the most used method for measuring road surface noise. This is also the recommended method in Europe. The paper presents partial results of the research project of the Technology Agency of the Czech Republic CK02000121 Determination of values of classification levels for evaluation of road surface noise in the Czech Republic. Its aim is to obtain suitable data from CPX measurements and to develop proposals for a possible noise assessment of surfaces. The relevant technical regulations could then be supplemented with this classification scale, which would help with an acoustic performance evaluation of surfaces within a surface characteristics or management system. From an acoustic point of view, road surfaces can be divided into 3 basic groups. These are conventional surfaces such as SMA, DAC, or EACC, high-noise pavements such as cobblestones, and low-noise pavements such as BBTM or grinding of cement concrete. High and low-noise pavements are acoustic extremes in both directions (high and low noise levels).
