RESEARCH BY U.I.C. INTO TYPES OF CONCRETE SLEEPER

The object of the tests is to compare in near-identical conditions: (1) The behavior in the track of various types of concrete sleepers and their fastenings; (2) behavior of track sections equipped with different types of concrete sleepers; and (3) costs of track-laying and maintenance operations. Periodical measurements, generally at six-monthly intervals, are taken of an Amsler track-recording coach; longitudinal levels to show general settlement; smoothness of riding; state of the surface of rails and welds creep, if any, of the long rails; movement of rails on pads or pads on sleepers; tension and condition of fastenings; any signs of cracking or spalling of the sleepers; and mechanical performance of the insulating components. Additional measurements are to be taken occasionally of the grading and shape of the ballast; Mauzin coach records; weight of particular sleepers; noise level; and static and dynamic track depression.
