Sažetak
Noise measurements in a vehicle with the purpose of determining riding comfort have been neglected and are rarely done, while considerable attention was paid to the state of noise next to a road in the sense of determining the noise levels in the area through which the road passes, and finding solutions for their reduction, if the measured noise levels were above the allowed ones. The mentioned facts stimulated a research with the goal of determining the noise levels in a vehicle in relation to different types of the pavement structure. Within reconstruction of pavements on the A3 (E70) motorway, rehabilitation of the Ilova bridge was carried out, where the existing asphalt pavement structure was replaced by the concrete one, while the pavement before and after the bridge was reconstructed with a new asphalt layer. Exactly due to different types of pavement, that section of the motorway was selected as the test polygon for the planned research. Besides measuring noise in a test vehicle, along with its movement speed, measuring of the pavement evenness was done on the pavement, expressed as the IRI parameter (International Roughness Index), which represents a usual datum about the state of the pavement that road authorities regularly collect. On the basis of the collected measurements data, the paper presents the relationship between the noise levels in the test vehicle, its movement speed and pavement evenness.
