Nuove esperienze sulla limitazione delle vibrazioni con conglomerati bituminosi e gomma riciclata – The limitation of vibration with bituminous conglomerates and recycled rubber: the last experiences

In some urban areas, such as those near historical sites, is extremely felt the disturb to people and buildings due to traffic vibrations. The paper deals with a study protocol finalized to design an high performance flexible pavement with anti-vibration properties to be used in the over mentioned situations. The influence of a selected percentage of the crumb rubber on the behaviour of a binder course asphalt concrete versus traffic vibrations has been investigated in laboratory as well as on field, in comparison with a traditional pavement having the binder course without crumb rubber, by the use of both traditional and innovative methodologies and devices. The results achieved show a better performance in reduction of traffic vibration and mechanical behaviour of the asphalt mix with granulated crumb rubber compared to the traditional binder course
