Managing Bridge Expansion Joint Noise with Geotextile

TransLink in British Columbia, Canada will install three materials to try and mitigate the noisiness of the expansion joints of the Golden Ears Bridge near Vancouver. Three materials are: a neoprene elastic-type product, similar to wetsuit material, that it already installed in one of the joints at the north end of the bridge; a spray foam made in Japan by a subsidiary of Mageba, the Swiss firm that made the steel expansion joints; and a geotextile fabric.
