USE OF ASPHALT MATERIALS IN RAILWAY LINE INFRASTRUCTURE

IMPIEGO DEI MATERIALI BITUMINOSI NELLA SOVRASTRUTTURA DELLE LINEE FERROVIARIE

For the first time in Italy, it has been decided to use a sealed asphalt mixture (partically impermeable) as base layer (under the ballast) to reinforce and protect the infrastructure of the new FS Rome-Florence Direttissima line because trains will travel at high speeds (250 km/h) and traffic will be dense (200 trains per day in both directions). It is important to distribute evenly the load transferred from the ballast to the embankment and to ensure perfect line layout. The article describes in detail the characteristics of the elements making up the asphalt mixture used and construction work on the new track formation.
