DEFORMATION OF RAILWAY BALLAST UNDER REPEATED LOADING CONDITIONS

The work described in this paper was concerned with the action of repetitively applied stresses on the deformation of track ballast and was confined to the tri-axial testing of dry ballast where the stresses can be accurately controlled. A major departure between this work and the more normal testing in the field of soil mechanics is that it is more usual to concentrate on the determination of the ultimate strength of the material, while here the main purpose is to determine deformations in the material at stresses often well below those which cause failure. At the present moment the work is in mid-program and both interpretation of the existing test results and also the complete test series have not yet been concluded. Therefore, this paper is by way of an interim report suggesting some ideas which may immediately have direct relevance to today's railways and also to act as a spur for work to be done to bring the knowledge of the material properties of ballast up to that of other engineering materials.
