Due to the fact that the bearing capacity of the soil as well as the CBR depend on relative compaction of the soil, three compactive efforts were chosen by changing the number of blows per layer of the soil sample compacted in 5 layers in the CBR mould by 10 lbs (4.54 kg) hammer falling from 18" (45.7 cm) height.
Some experimental data from the literature (Sinha and Wang, 2008) are used to develop the EPR models.Table 1 includes the gradation properties of soils, Table 2 contains the compaction test data as well as some physical properties, and Table 3 summarizes the permeability test data. Data are from a soil made of four different major …

The soil water retention curve (WRC) is a fundamental soil hydraulic characteristic that describes the relationship between the soil matric potential (or capillary head), ψ and the volumetric water content, θ. It is indispensable for the solution of the equations that describe water flow processes in soils (Assouline and Or, 2013).
