Falling Head Permeability Test
The falling head permeability test is a common laboratory testing method used to determine the
permeability of fine grained soils with intermediate and low permeability such as silts and clays.

In this lab Students will demonstrate how different sieves can be used to divide up different
aggregates. The sieves are different sized filters that are stacked on top of each other and when
they are shaken over a

Steps you need to take for the assessment of borrowing
soil to a project to fill onsite.
1. The first step that a Geo Engineer will need to do to is calculating the
volume of soil needed for filling your site.
2. Next they will need to determine the type

Aggregates are processed for use as a Portland cement concrete by first washing the aggregate.
Next the aggregate is put through a heavy media separation which uses specific gravity to divide
the aggregate into the desired type. Next they use elastic

which the asphalt will ignite. The asphalt is slowly heated as an open flame passes over it until ignition.
