BITUMINOUS CONGLOMERATE AS A NEW SOLUTION FOR THE UNDER - BALLAST LAYER ON RAILWAY LINES: SCALING WITH A DYNAMIC METHOD

The resistance to fatigue, the property of self-repair, the impermeability and resistance to freezing are the main characteristics which induced the introduction of bituminous conglomerate in the 1st and 4th sections of the new direct line, Rome-Florence, as an alternative to "sub-ballast" in cement mixture. The thickness of the stratum was determined, in addition to the CBR method, by a special procedure of calculation which takes account of the dynamic modules of the materials and which can be verified in situ.
