THE PRACTICE OF DIRECT ATTACHMENT OF RAILTRACKS ON TO VIADUCTS

L'IMPIEGO DI ATTACCHI DIRETTI DELLE ROTAIE SUI VIADOTTI

The direct attachment of rails (without the use of crushed stone ballast) onto tunnel or viaduct structures is increasingly practised in many countries, especially in Metro systems. This study analyses the stresses and deformations caused by temperature variations in the case of railtrack attached directly on to a viaduct. A comparison is made to conditions and behaviour when supported on ballast. (TRRL)
