Collapsible soils type are in nature unsaturated soils, which are characterized by a metastable structure and undergo an abrupt collapse when they are flooded (with or without loading), which causes important damage. Based on the structural composition of these soils, we reconstituted the samples made up of sand and fine particles occurring in various proportions. The first phase of the work consists in the experimental determination of the geotechnical characteristics of these samples. It is thereafter proposed a test program based primarily on the use of the cone penetrometer and the ultrasonic apparatus allowing the factors which influence collapse to be predicted. The results obtained clearly show the influence of certain parameters such as water content and the energy of compaction on the collapse potential and the ultrasonic speed.
