TEST ON CHARACTERISTICS OF BALLASTED TRACK LAID ON SOIL ROADBED

T Nagafuji, Takatoshi Noguchi

Abstract

Relating to the new theory on deterioration of track including the soil subgrade, various loading tests were carried out to explain the characteristics of ballasted track laid on soil subgrade. Static and dynamic properties were classified and the effects of load magnitude, watering and tamping on the subsidence of track were made clear. These test results will yield data for investigation on the characteristics of ballasted track.
