| Abstract | This paper presents a study of the effect of relative density and moisture content on the resilient behavior of subgrade soils in Saudi Arabia. Thirteen representative soil samples, representing subgrade soils nom all over the Kingdom, were tested at two different relative densities (93% and 96%) and the corresponding moisture contents on the compaction curves in addition to the optimum moisture content and maximum density. The results show that the resilient behavior depends on soil type (fine grained or granular) as well as moisture content and relative density. The study shows that both moisture content and relative density governs the effect of deviator and confining stresses on MR behavior. The study emphasized the importance of using a model that describes correctly the dependency of MRon both confining and deviator stresses. Keywords: resilient modulus, sub grade soil, modeling, |
