Life Cycle Cost and Performance of Lightweight Noise Barrier Materials Along Bridge Structures

The site of this study is on elevated eastbound sections of lH-30, west of downtown Dallas. They are located north of the Kessler Park Neighborhood where the CTR team conducted a major sound project in 201 0/201 1 on westbound sections of an extensive retaining wall. Two locations in the Dallas District are segments between Sylvan Avenue and Edgefield Avenue, with an approximate length of 2,500 ft, possessing a concrete sound wall approximately 8-ft. in height. The second segment is from Sylvan Avenue to Beckley Avenue, which has a traditional safety barrier rather than a dedicated concrete reflective sound wall and is approximately 4,000-ft. long. The research team will evaluate the performance of a light-weight traffic noise wall for both sections which will extend the height of the existing walls and so both attenuate sound propagation and block the current line of sight from the adjacent neighborhood to the highway. The CTR team will conduct a feasibility study using Dallas District staff and industry contacts. This study will develop the comprehensive work plan needed to answer the issues raised and identify the research components integrate the research activities with the sound wall bidding, construction and maintenance activities which managed separately by the Dallas District. It will allow the subsequent study to capture sound measurements and life cycle impacts at key locations before and after the construction of the lightweight sound walls before fall 2013. The measurement of sound absorption or reflection (depending on the type selected by the Dallas team) needs to be undertaken during regular cycles of weather, including wind and temperature changes, starting in winter 2013.
