This paper describes the results of a laboratory investigation aimed at understanding the behaviour of a dense silty sand subjected to different loading histories. Several factors, including degradation by cyclic loading, moulding water, lime addition and creep stages, are considered. Results showed that optimum compacted materials have bigger stiffness and lower damping ratio comparing with dry and wet materials. It was also seen that creep stages influence the subsequent stress-strain behaviour in a limited strain range, or for the whole subsequent behaviour. Beneficial effects of lime addition appeared in terms of increase in stiffness, reduction in damping ratio, reduction in cyclic degradation and increase in shear strength.
