A DRAINING CEMENT CONCRETE ROAD SURFACE THAT PRODUCES LESS THAN 73 DB
One major expectation for road users is related to noise attenuation. Theory indicates that a thick porous pavement would provide good results. In terms of tire noise, the draining cement concrete used as subbase had not been tested for tire noise until recently, when a construction of a test site was done in France. The objectives were to verify the feasibility of 16-cm (6.2 inch) thicknesses of draining concrete that could meet the same roughness requirements as the national system i.e., a roughness level, expressed in CATL, of 6 or less throughout the site. The results show that the draining cement concrete formula used in the experiment ranks among the best pavement materials in terms of road noise, since all objectives were reached with respect to acoustical performance, hydraulics, and ride quality.
