Introduction
Soil gradation is an important aspect of geotechnical engineering. It is an indicator of other engineering properties such as compressibility, shear strength, and hydraulic conductivity. In a design, the gradation of the in situ or on site soil often controls the design and ground water drainage of the site. When a fill material is being selected for a project such as a highway embankment or earthen dam, the soil gradation is considered. These types of projects may also have gradation requirements that must be met before the soil to be used is accepted. When options for ground remediation techniques are being selected, the soil gradation is a controlling factor.

Soil Gradations

 * 1) Well Graded
 * 2) Poorly Graded
 * 3) Uniformly-Graded
 * 4) Gap-Graded
