Summary

Large-scale tests were performed to compare the lateral resistance that develops between ties (or sleepers) and two types of ballast material. Ballast Type 1 consists of crushed, angular to sub-angular particles, and is an important source of ballast material in Western Canada. Ballast Type 2, crushed Gravel Ballast, contains rounded and crushed angular particles. Three components of the tie/ballast interface provide lateral resistance within a track system: base resistance, crib (side) resistance, and shoulder (end) resistance. The base resistance, which is a function of normal load, was investigated and reported in this paper. The effects of the crib and shoulder ballast are to be determined in a subsequent test. Normal loads between 5 kN and 160 kN were applied during testing, and are representative of the expected range of in-service train loads transferred to an individual railway tie. Preliminary results indicate that on average 9.4% less lateral resistance is developed between the tie and the gravel ballast than the McAbee ballast.
