LABORATORY PERFORMANCE OF RAILROAD BALLAST

Vibration, one-dimensional repeated loading and standard triaxial test results on a railroad ballast are presented. The vibration tests were performed in an oedometer using independently variable vertical amplitudes, frequencies and surcharge pressures. The repeated load tests were also performed in an oedometer to study the influence of initial density, loading intensity and ballast grading. The main properties obtained from the above tests are the vibration characteristics, strength, stress-strain characteristics, density and disintegration of the ballast.
