Draining asphalt

Case studies

Autostrade per l'Italia aims to continuously increase service levels. Motorist safety is a key objective, to be achieved thanks to innovations such as draining asphalt, which translates as greater visibility and driving comfort.

Research and innovation has always set Autostrade per l'Italia apart, even as regards the materials used along the road network. Group commitment to improving travel safety standards can be seen in the use of draining asphalt, which has increased exponentially since 1999 (first year of the concession) to date.

Draining Asphalt: continuous progress

Draining asphalt improves visibility and driving comfort in the rain, while at the same time reducing aquaplaning and noise pollution risk: in short, the greater the number of kilometres are paved with rain-resistant asphalt, the greater is motorist safety. Taking Autostrade per l'Italia subsidiaries into account also, at the end of 2011, draining asphalt had been laid on 80% of the 3,095.5 km Group network as at the end of 2011 (100% of the network considering that the remaining 20% consists of mountain stretches, tunnels and work in progress, unsuited to draining asphalt) compared to just 18% in 1999.

New paving on completion of works

The laying of draining asphalt is now complete: traditional asphalt is now only to be found in tunnels and mountain stretches, which are unsuited to rain-resistant asphalt.
Autostrade per l'Italia is in the process of laying high-durability, rain-resistant asphalt where possible. 11% of the highway is paved with new-generation asphalt.
