Low visual impact soundproof panels for reduced traffic noise: an innovative Italian proposal

This study investigated the effectiveness of precast concrete noise barriers and connecting pillars with an aesthetic external finish resembling random block size stonework. The panels are manufactures with 30MPa concrete, with a photo-catalytic colouring admixture and reinforced with square steel mats. The barrier system was erected a few miles away from Potenza, Italy, next to a new rural road used by heavy lorries to reduce noise affecting a church. The installation procedure required an initial phase of ground clearing and a subsequent layer of concrete in order to achieve a uniform surface, needed to evenly distribute loads and avoid differential deflections. Use of the panels reduced the traffic noise by about 15dB(A) during the week. It is considered possible that a noise reduction of more than 20dB(A) would be achieved if the use of the barrier was combined with noise-reducing pavements.
