Many problems are generated by the presence of water from different sources in a pavement structure. The infiltration characteristics of the sub-base are an important component of the hydrological conditions. They are one of the components of the water balance and are necessary to describe the runoff response by a runoff model, in addition to describe the effect of water movement on changing the soil properties within infiltration.
The present work emphasis on the characteristics of the infiltration by using laboratory model. This model is performed on compacted sub-base samples of specific density and different heights, 10, 15, and 20cm, for different heads of water, 10, 15, and 20cm. The results revealed that there is a significant effect of water head and height of sub-base layer on the infiltration with high interaction of the wetting conditions of the sample. A statistical analysis was made to develop a relationship among the different studied parameters.
