Özet

Anisotropy is an important characteristic of granular material but has normally been neglected in the design of pavement structures. There has been little or no work on the anisotropy of granular materials for pavement construction. This may be due to the difficulty of testing of coarse granular material. In the study, resilient anisotropic characteristics of granular materials were measured using the repeated load triaxial apparatus. Both inherent and stress-induced anisotropy were measured. Test results indicated that different materials have different anisotropic properties. Results also indicated that it is quite difficult to establish a pattern for change in anisotropy.
