This is an experimental study on an actual topic of collapsible soils, which has offered a range of diversified applications. These soils are characterized by the unsaturation and the abrupt collapse after wetting, located in many parts of the world, especially when they are arid or semi-arid. These types of soils are located in a significant number of countries in particular those of the northern hemisphere between the 30th and 55th parallels as well as countries of South America. The cycles of prolonged dryness which occurred in the past years on several occasions and in several regions of the world modified the parameters governing the behavior of the soil and gave rise to new collapsible soils zones. The results of the tests of this experimental study, conducted on reconstituted soils in a large number of tests, indicated the influence of the parameters retained on the collapse potential, the migration of fines and the ultrasonic speeds. Similarly, the fine particles played an important role in the formation of macroporous loose structures.
