NEW SNCF CONCRETE SLEEPERS

LES NOUVELLES TRAVERSES EN BETON DE LA SNCF

After outlining the history of the use of concrete sleepers and describing their technical characteristics, the study on stresses in the track, caused by dynamic overloading, is based on the work of an ORE Specialists Committee (Question D 71) and the experience acquired by the SNCF in the calculation of the maximum stresses to be taken into consideration. So as to be able to compare the performance of the different sleepers and check the results obtained by experiment against behaviour in service, the SNCF decided to have the following types manufactured: composite reinforced concrete sleepers (VAX V30 and SL V 30); monobloc prestressed concrete sleepers; composite "PRETUBE" sleepers in which an extrusion tube serves as a tie-bar and a means of obtaining prestressing.
