APPLICATION OF NOISE BARRIERS WITH RUBBER CONCRETE ON CERTAIN SECTIONS OF THE SOUTHERN BYPASS OF OSIJEK

Concrete is the most frequently used construction materials nowadays. Constant development of new technology, combined with ever-growing needs of contractors and investors has uncovered new economical, aesthetical and structural demands that concrete needs to satisfy. Scientists began to experiment with recycled materials that could enrich concrete properties, such as: rubber, styrophoam and hemp. The goal of this paper is to establish the influence of rubber aggregate on properties of concrete in fresh and hardened condition. Three concrete mixes were used for properties of fresh and hardened concrete analysis. Examples of successful use of rubber concrete in the past have been reviewed, such as its implementation in concrete noise barriers. Level of noise canceling efficiency has been measured on the South Osijek freeway, before and after noise barriers were placed there. In addition, another goal of this paper is establishing whether placing those barriers in South Osijek freeway would help decrease noise pollution that affects those citizens that inhabit apartments near the aforementioned freeway. At the conclusion, we have shown the difference that noise barriers make in areas where the level of noise pollution was higher than city code allows.
