Parallel to the construction of new roads and the maintenance of existing ones, activities that absorb substantial economic resources, the study and development of technical solutions aimed at improving road performance with regard to reliability, safety and comfort have received just as much attention in recent years.

In this context, one of the areas of research with a strong potential for development is the use of rubber deriving from the recovery of end-of-life tyres (ELT) as an additive in bituminous conglomerates to create high-performance “modified asphalts”. Ecopneus has played an active part in various experiments throughout the country, in Caserta, Bologna, the Province of Turin, Bolzano, and Trento, just to mention the main ones.

Roads built with “modified asphalts” with rubber powder have many advantages:

high durability of the pavement and exceptional resistance to aging, with international experiences of lifetimes up to three times longer than those of traditional asphalt;
consequent significant containment of maintenance interventions and costs;
appreciable reduction in noise;
excellent drainage in wet weather, with a strong improvement in visibility;
excellent response in case of sudden braking;
use of a resource deriving from the recycling of decommissioned tyres, an operation with an important environmental value.
