Title: DEFORMATION OF RAILWAY BALLAST UNDER REPEATED LOADING CONDITIONS
Abstract: Testing of triaxial samples of ballast where the boundary stress conditions are known provides a rapid method of doing comparative tests on ballast to highlight the relative significance of the different loading conditions in causing permanent deformation of ballast. The paper initially considers the effect of the packing condition of the ballast and the grading of the material on the permanent deformation. It then considers the effect of different stress conditions on the basic deformational properties of the ballast and concludes with examination of the synthesis of different traffic patterns, examining such factors as frequency (speed) and programme patterns (2 levels) of loading.
