Croatian Experience in Road Traffic Noise Management - Concrete Noise Barriers

Abstract

The paper gives an overview of concrete noise barrier application in several EU countries and in Croatia. It describes a process of introducing different noise protection solutions on Croatian market in the phase of intensive motorway construction in recent years. Namely, an extensive motorway network has been constructed in Croatia in the last 10 years. Following the process of motorway construction, noise protection walls have also been erected. Usage of different building materials and installation processes as well as variations in building expenditures has led to a comparative analysis of several types of noise protection solutions (expanded clay, wood fibre) including a new eco-innovative product RUCONBAR, which incorporates rubber granules from recycled waste tyres to form a porous noise absorptive layer.

Assessment of Traffic Noise Pollution Due to Urban Residential Road Transport

“…1), therefore obtaining results for all buildings on the street and in the residential area are unique. Our approach present results of 3d noise mapping for all residential zones, which is more efficienct to evaluate assessment of the bariers needs.An analysis of existing mathematical models [11][12][13][14][15][16][17][18] for determining the expected noise level (L) of a traffic flow allows us to conclude that most of the forecasting models have the following form:…”

“…At present, the huge practical experience of using various noise protection measures for reducing road transport noise is accumulated [10]. In Brazil [11], USA [12], Serbia [13], Italy [14], Canada [15], Romania [16], India [17] and other countries [18] tens of thousands of kilometers of acoustic screens are installed. Slovakia, France and Germany use a noise-absorbing road surface to reduce the noise of car tires [19].…”

Progress on Noise Reduction in Road Traffic Environment from 2000

“…Unlike Luca Fredianelli, Alessandro Del Pizzo and Gaetano Licitra, most of the other researchers combined low-height barriers with vegetated barriers and evaluate the properties through multiple ways, including case studies. Real-life applications, 3D simulation and multi-dimensional analysis [3][4][5][6]. Timothy Van Renterghem et al's study reached that the result of reduction in dB is slightly lower than the green barriers in previous literature.…”

Desarrollo De Modelos De Comportamiento Acústico Y Caracterización Experimental De Materiales Elaborados Con Aligerantes Para La Construcción. Aplicación a Sistemas De Control De Ruido.

“…En esta referencia se concluye que los paneles con agregado de arlita presentan un rango estrecho de frecuencias con absorción adecuada, mientras que otros agregados, como pueden ser el reciclado de neumáticos, ofrecen un mayor rango de frecuencias para absorción alta. Otra aplicación de arlita en paneles de absorción acústica se muestra en las referencias de Lakušić et al ( [154] y [155]) y Ahac et al [7] donde se comparan las capacidades acústicas de paneles con hormigones aligerados con arlita y paneles de madera y se introduce un nuevo producto derivado de la reciclabilidad de neumáticos fuera de uso como material de aporte en el hormigonado. En Turkiewicz y Wszolek [288] se estudia la absorción acústica de placas de hormigón aligerado con arlita en cámara reverberante.…”
