Abstract: The saturated fine grained soils are prone to liquefy under low amplitude vibrations. The normal operations of highways constructed over these soils might be seriously affected. In order to minimize the adverse liquefaction effect of fine grained soils during the construction, the impact of low amplitude vibration on the soil permeability is studied using laboratory and field tests. It is concluded that, as the number of vibrations increases, the measured coefficient of permeability tends to first decrease and then decrease for different types of soils. The grain size, gradation and the void ratio of the soils have the significant effect on the soil permeability.
