Noise barrier to reduce acoustic pollution<\/h2>\n

Innovative noise barriers<\/strong> in expanded clay concrete to protect inhabited areas from noise pollution coming from the A4 highway, one of the most important road arteries that crosses northern Italy from west to east.<\/p>\n

During the expansion works between Quarto d’Altino and San Don\u00e0 di Piave, heavy traffic, mainly involving heavy vehicles, required the use of a suitable noise absorption solution, especially on the new embankments near the small agglomerations of houses along the stretch managed by Autovie Venete.<\/p>\n

In fact, when building strategic infrastructure works, increasing attention is paid to compatibility with the surrounding area. For this reason, in the case of highways, soundproofing<\/strong> is a fundamental element. Noise barriers, which have been placed on both sides along a stretch of about ten kilometres, consist of prefabricated reinforced concrete panels and expanded clay concrete soundproofing slabs.<\/p>\n

This particular solution, which thanks to the stratigraphy and geometric conformation of the surface, has high absorbent properties and a sustainable core.<\/p>\n

A new product born from the circular economy<\/h2>\n

An important contribution came from the Pittini Group<\/strong>, both in terms of production efficiency and sustainability. The Granella\u00ae<\/a> product, obtained from steel production waste, is used as an artificial aggregate in the construction of bituminous layers, cement concrete and concrete mixes.<\/p>\n
