Longitudinal and Lateral Resistant Characteristics of Ladder Sleeper

Michiaki OYADO, Hiromi INOUE, Seiichi TOTTORI
Longitudinal and lateral resistant characteristics of the ballasted Ladder Track are experimentally investigated. As the result of the loading test, longitudinal bearing capacity is found to be about 10kN/m. Using the above-mentioned test result, continuous welded rail (CWR) elongation due to temperature change is simulated by the program TIDACS.
Lateral bearing capacity is evaluated by the loading test, too. It is obvious that lateral bearing capacity of the ballasted Ladder Track is about twice that of the conventional ballasted track.
