Abstract


There are different factors that can affect the life quality and involve different areas of human activity, especially in urban areas. Noise and vibration are two elements to which people are more susceptible, because sometimes they can affect the physical and mental well-being. The process of industrialization and motorization can be considered as the main reason for the existence of these two factors. For example, the vibrations generated by road traffic, as well as being a source of trouble for residents, can cause damage to buildings and equipment in the areas close to roads. Sometimes it interferes with activities such as those carried out in operating rooms or in precision laboratories. Several legislative solutions have been undertaken in recent years, to decrease road noise, even if the efforts to reduce vibrations are not appropriate to the level of damage done. Experts and researchers around the world have been studying solutions aimed at the mitigation of these disturbing elements. Interesting studies have been carried out on road paving construction materials which are be capable of reducing vibrations caused by road traffic.Iterchimica’s researchers have developed a special technology based on the use of rubber powder derived from recycled tyres at the end of their service life, which can reduce vibration and the resulting rolling noise. In reference to the latter the results of a study conducted in collaboration with iPOOL srl, a spin-off of the Italian National Research Council (CNR) are reported.
