Sažetak
In its nutshell, RUCONBAR (RUbberized COncrete Noise BARrier) is a concrete based solution composed of an absorbing and a bearing layer. Its absorbing layer is made of recycled waste tires and concrete. By incorporating in its absorptive layer 40 % of rubber granules recycled from old automobile tires, an innovative product has been created, which is a novel solution in the sphere of noise protection, unique on the market. RUCONBAR concept is an economical, easy to implement, and environmentally sound noise protection solution. For orientation, 46.4 t of recycled rubber granules, obtained by recycling 7.800 waste car tires, can be used for manufacturing 1 kilometer of noise barriers 3 m in height (3, 000 square meters of barriers). Sound absorption category A3 (8 to 11 dB) according to EN 1793-1:2013 can be achieved by varying the thickness and shape of absorbing layer. Category A4 (12 to 15 dB) can be achieved for special purpose applications. The first application of this novel innovative noise protection barrier was made on a road section near toll booths for Krk Bridge in Croatia. Following this example, RUCONBAR walls are being constructed on different road and railway sections. Major environmental benefits of using RUCONBAR are: - 31% reduction in GHG emissions compared to similar solutions available on the market, - reduced consumption of non-renewable resources (gravel or crushed stones, natural clay and tree felling), - protection of natural environment against uncontrolled clay excavation and tree felling practices, - recycling end-of-life car tires.
