Algeria is nowadays bustling with extensive infrastructure projects (highways, roads, railways, etc) where most of them are planned to be constructed over areas covered with Sabkha soils. These soils are recent saline sediments widely distributed in Algeria and other countries. In this study, the effect of water salinity on the compaction characteristics of the Sabkha soils of Chott El-Hodna (Algeria) was investigated. The standard Proctor tests were performed using distilled water and Sabkha brine, and the compaction characteristics were determined using conventional water content and fluid content methods. The results indicate that the conventional water content procedure used to plot the compaction curve overestimate the maximum dry unit weight and underestimate the optimum moisture content.
