An experimental research on the properties of Sicilian railroad ballast aggregates to the EN 13450:2002

Risultato della ricerca: Otherpeer review

Abstract

For the usual railway track, the railroad ballast is an fundamental factor forequally distributing all the loads and for drainage purposes. The railroad ballast still helps to correcteventual problems while building the railway. The railroad ballast aggregates have to be giftedwith specific requisites in terms of physical and mechanical characteristics.The European Standard EN 13450:2002 specifies the properties of aggregates obtained by processingnatural or manufactured materials or recycled crushed unbound aggregates for use in constructionof railway track. Such standard provides for the evaluation of conformity of products tothis European Standard.The knowledge of ballast characteristics is indispensable to make modeling that correctly showsthe mechanical behaviour of railway track to the loading applied when a train runs on a regular track.An experimental research has been carried out, focused on conformity of some aggregates tothe UNI EN 13450:2003 and on properties being useful to describe the mechanical behaviour ofballast.
