TEST ON CHARACTERISTICS OF BALLASTED TRACK LAID ON REINFORCED SOIL SUBGRADE

Tests were run on the static and dynamic characteristics of ballasted track laid on a reinforced soil subgrade where reinforcement consists of a 5-cm thickness of asphalt concrete covered by asphalt emulsion atop 45-cm bed of grain-sized crushed stone. Static loading, frequency response and fatigue tests were carried out by an oil-pressure loading device on a test track panel; the fourth test was a fixed type wheelset dropping device. Further tests are planned with this construction on embankments and in cuts.
