A FORMATION OF BITUMINOUS CONGLOMERATE FOR THE NEW LINES: THE EXPERIENCE GAINED ON THE ROME-FLORENCE "DIRETTISSIMA"

Impermeability, resistance to frost and to fatigue and the property of self-repair form the most important characteristics which have favored the use of bituminous conglomerates, as an alternative to the ballast foundation of cemented aggregate, for the construction of the formation on the new Rome-Florence "Direttissima" of the Italian Railways. The thickness of the layer was determined by a method of calculation based on the dynamic characteristics of the material and checked by means of the tables for the dimensioning of flexible pavings, then verified in situ by means of tests, the most outstanding features of which are described in this article.
