Volume 41, Issue 1
  • ISSN : 1021-2019



The objective of this paper is to investigate and quantify the resilient behaviour of the ballast pavement layer by means of dynamic triaxial testing. Factors affecting dynamic triaxial testing on granular material were analysed by means of a literature study and are summarized for convenience. The maximum principal stress difference and the degree of fouling were varied during the triaxial tests. Relationships for the prediction of the resilient modulus are presented.
