AB  - Road transport has been the dominant source of noise in the environment for many years and most of the noise is nowadays generated by the interaction of the tyre with the road, beginning with relatively low speeds. The condition of the road wearing course is the factor that particularly influences the noise pollution generated by the movement of vehicles on roads. The CPX method (CloseProXimity) used for measuring the amount of noise from the rolling of tyres consists of drawing a special trailer fitted with reference test tyres that are surrounded by microphones recording the noise generated by the rolling tyres along a test section. This dynamic method allows the evaluation the noise from the road surface in the field for the full length of the examined road section. It can be performed during the normal operation of the road with no need for traffic restrictions. Monitoring and early exchange of road surface can significantly contribute to the sustainable development of transport and a reduction of its negative impacts on the environment and human health thanks to the effective reduction of the excessive noise from road traffic. This paper presents the process of field measuring tests with a subsequent evaluation of results.
