Tire/Road Noise on Rubberized Asphalt and Cement Concrete Surfaces in Sweden
Three road surfaces of the RUBIT type, i.e., asphaltic concrete mixed with rubber granulate, so-called rubberized asphalt, have been tested for external noise emission. These have been compared with a conventional, smooth asphaltic concrete surface (HAB12T) and a conventional, rough chip seal surface (Y1 8-12). Similarly, three cement concrete surfaces have been tested in a parallel project where the same reference surfaces were used. The RUBIT surfaces all contained 3% rubber and 12 mm maximum chip size. They were, however, in somewhat different conditions; one surface being quite new and one being two years old and densely trafficked. The tests have been performed with the so-called trailer method. A special trailer constructed to measure tire/road noise, from the Technical University of Gdansk, has been used. Sound levels as well as frequency spectra have been measured.
