Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass
ASTM Standard: D-2216
Most laboratory tests in soil mechanics require determination of the water content.
Specific Gravity of Soil Solids by Water Pycnometer
ASTM Standard: D-854 , C-157
The specific gravity of a given material is defined as the ratio of the density of a given volume of the material to the density of an equal volume of distilled water. In soil mechanics, the specific gravity of soil solids (which is often referred to as the specific gravity of soil) is an important parameter for calculating the weight–volume relationship.
Sieve Analysis
ASTM Standard: D-422
In order to classify a soil for engineering purposes, one needs to know the distribution of the grain sizes in a given soil mass. Sieve analysis is a method used to determine the grain size distribution of soils.
Hydrometer Analysis
ASTM: Standard: D-422
Hydrometer analysis is the procedure generally adopted for determining the particle-size distribution in a soil for the fraction that is finer than U.S. No. 200 sieve size (0.075 mm).
Liquid Limit
ASTM Standard: D-4318
When a cohesive soil is mixed with an excessive amount of water, it will be in a somewhat liquid state and flow like a liquid. However, when this viscous liquid is dried gradually, with the loss of moisture, it will pass into a plastic state. With further reduction of moisture, the soil will pass into a semisolid and then into a solid state…
Engineering Classification of Soils (AASHTO, USCS)
ASTM Standard: D-3282, D-2487
Soils vary widely in their grain-size distributions . Also, depending on the type and quantity of clay minerals present, the plastic properties of soils may be very different. Various types of engineering work require the identification and classification of soil in the field.
Proctor Compaction (Standard, Modified)
ASTM Standard: D-698, D-1557
For the construction of highways, airports, and other structures, it is often necessary to compact soil to improve its strength.
Direct Shear
ASTM Standard: D-3080
The shear strength of a given soil can be expressed by Mohr-Coulomb failure criteria.
