Noise reducing asphalts: a priority issue for the Region of Waterloo

Four asphalt mixes were placed to conduct the noise testing: rubber-modified open friction course, rubber-modified open graded course, stone mastic asphalt and hot mix HL-3. The purpose of the testing was to measure the noise characteristics of the different asphalt mixes in order to conclude whether there was a noise reduction benefit associated with the special mixes that would warrant their use in urban noise-sensitive areas to reduce or eliminate the need for other noise mitigation measures, including noise walls. Noise level test results have indicated that the special premium pavement mixes do achieve a reduction in measured noise. The reduced noise levels are attributable to a reduction in the duration of exposure to noise observed with the special open-graded mixes.
