LATERAL STABILITY OF BALLAST--BALLAST AND FOUNDATION MATERIALS RESEARCH PROGRAM
This report presents the results of the lateral stability study of the Ballast and Foundation Materials Research Program. Full-scale lateral stability tests were conducted with a 2-rail, 3-tie system using slag, crushed limestone, and gravel as ballast. Various parameters including Peak Resisting Force and Displacement at Peak Resistance were chosen as possible measures of lateral stability. The results of the study indicate that the differences in the lateral stability behavior of the three ballasts tested is not significant. Also, the results indicate a peak L/V (lateral resistance/vertical force) ratio of about 0.8.
