Concrete road pavement guarantees the durability of the mechanical characteristics of the pavement (no rutting), uniformity of surface and grip on the road.
Using concrete for road pavements in tunnels, leads to following advantages:
Reduction of maintenance cycles and consequently fewer road works, less tunnel closing with diversion itineraries, causing environmental nuisance.
Restriction of road works in the presence of road users and hence less workers on site, representing a possible source of accidents.
