An investigation conducted during the period May 1976 to April 1977 to study the behaviour of granular-type materials used in railroad track is reported. This work entailed three sections: investigations of the properties of ballast, which include oedometer repeated loading tests, vibration tests, and triaxial static and repeated loading tests on four sample ballast materials; testing of model plane strain footings of different widths under static and repeated loading conditions; and testing of a circular footing under static loading. The work on the properties of ballast represents an extension of that reported in CIGGT Report No. 75-10 and especially in CIGGT Report No. 76-11. An orthogonal experiment based on the hardness-toughness dimensions identified during the past year was designed, with one ballast representing each quadrant of the matrix.
