Sand Equivalents Quality in California
Apr 30, 2011 · The test results are a number but it is a percentage of good material in your sample. So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental.

These results are then compared to a standard curve for a value of CBR. The forces on the standard curve are 13.2kN at 2.5mm penetration and 20.0kN at 5.0mm penetration. The CBR is then a simple ratio of the corresponding values and where a difference between the value at 2.5mm and 5mm occurs, the higher value is taken.

Atterberg limits Wikipedia
The Atterberg limits are a basic measure of the critical water contents of a finegrained soil: its shrinkage limit, plastic limit, and liquid limit.. Depending on its water content, a soil may appear in one of four states: solid, semisolid, plastic and liquid each state, the consistency and behavior of a soil is different and consequently so are its engineering properties.

Soil classifiion
The relationship between MCV and water content for a soil is near to a straight line, except for heavily overconsolidated clays.A desired value of undrained strength or compressibility can be related to limiting water content, and so the MCV can be used as a control value after calibrating MCV vs w for the soil.
