Permeability –
The constant head permeability test in the sand is functional to decide the permeability
and hydraulic conductivity of the sample. This test gives significant importance for engineers
since it allows them learn how fast water flows through the soil. When the water flows frequently
through their soil, it reduces the settlement potential. The constant head permeability test can
establish the system's permeability. During the experiment, the sample is described as tan with
fine grain. The standard specifies that this experiment uses laminar flow through granular solids
because this is “a natural deposit in embankments or when used as base courses under
pavements” (ASTM International). Concluding this lab, the anticipated results are an invalid
ration of a specimen, the coefficient of permeability and the dry density of the specimen. Each of
these can aid engineers decided if their foundation is stable.

Variations in the soil are used in the distinction of the soils that are to have structure built on
them. Soils retain water when wet, and some’s volume get bigger. The amount of water the soil
can take in is correlated to how much it will expand. The tests the students will perform are in
majority used on silty & clayey soils, due to these being the soils that shrink or expand due to
moisture content. These experiments are crucial for the beginning of any project, to see if the soil
will have the allowable amount of strength and not much volume change due to varying moisture
contents to support the structure that will be built on top.
