gradings for rail track ballast stone

RAILROAD BALLAST SIZING AND GRADING

Railroad ballast gradings tend, not only in North America but also world wide, to be uniformly graded (ie, single sized with the opening of the major percent passing sieve being 153 times the size of the percent retained on sieve) Herein a laboratory examination of ballastTo identify the ballast grading for heavyhaul rail track, monotonic and cyclic triaxial tests are conducted to assess the performances of different gradings Permanent deformations, aggregates degradation, resilience, shear resistance, maximum and minimum densities are recorded and analysed The grading is found to affect the behaviour ofIdentification of ballast grading for rail track
