WebVariable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow water to flow its pores or voids. WebMar 6, 2024 · The constant head permeability test is a laboratory method used to measure the permeability of soil. Sand and gravel are appropriate soils for these tests. This method cannot be used to test silty soils. The test can be used to evaluate granular soils that have been reconstituted or disturbed. Fig.1. Constant Head Permeameter
Webthe permeability tests. The soil was separated into five different frac- tions representing five different ranges in precompaction clod sizes. Soil from each of the soil fractions was used for soil specimens. The soil for the large-scale permeameter was compacted in two 7.62-cm (3-in) lifts. Small-scale, constant-head permeability tests also ...
