Geotechnical Laboratory Whether you need advanced geotechnical analysis or general soil classification, EGS has the capacity to accomplish a job of any size with a full time engineer on staff in our laboratory, you can be assured that you are getting the highest quality data in the business. Hydrometer Analysis of Soil Test Purpose: To determine the permeability of cohesive soils by the falling head method. Specific Gravity of Soil Test Purpose: D412 sample is prepared according to FM Varying amounts of soil are needed depending on the physical tests required for classification.

Qstm is broken into two different procedures: To determine the specific gravity of soils. Resistivity of Soil and Water FM To asfm the particle size distribution of soils finer than 0.

A minimum of grams is required to perform this test. Test can be performed using either a fixed ring or floating ring or floating ring consolidation cell. Normally 4 days or less.

A shelby tube sample is needed to perform this procedure. Normally 7 days or less. Contact our laboratory for more information on sample size and shipping options. To determine the Unified soil classification of a given sample. A minimum of grams is required for the procedure. Moisture Content of Soil Test Purpose: Three full 5-gallon buckets of material are needed for this procedure.

Sample size varies depending on the test specification requested. To determine the sulfate value of soil and water. To determine the unconfined compressive strength of an undisturbed cohesive soil. Sample size varies depending on the test procedure and estimated material type.

Where other physical tests are performed, moisture contents are included for no additional charge. Moist samples are first dried out to constant mass in the convection oven, then the sample is pulverized, split, and reduced to the required size.

To evaluate the bearing properties of samples that are used for base, stabilized subgrade, subgrade, or embankment material used in the state of Florida.

d4421 To determine the percentage of moisture that is present in a given soil sample. Normally 3 days or less. To determine the chloride value of soil and water. This test is required for soil classification purposes for cohesive soils.

An average specific gravity is developed from three different sets of tests.

Normally 24 hours or less. To determine the 3-day and 7-day compressive strength of a soil-cement series. Standard Proctor Test Test Purpose: Dry Preparation of Soil Test Purpose: Time dependant on material type encountered. Resistivity of Soil and Water Test Purpose: This procedure only applies to cohesive soils.

To aid in preparing a sample for other physical tests. Modified Proctor Test FM To determine the maximum density and optimum water content of a sample using standard effort.

The standard EGS sieve set is as follows: Please asrm Tom Hayden, P. Sample size varies depending on the sample gradation results and material type.

Normally 5 days or less. A minimum of grams of moist soil is needed to perform this test.
