Since moving into our current office location in February 2007, the added space has allowed us to develop an “in-house soils and construction materials testing laboratory. The ability to store and test soils and construction materials at our facility, in lieu of using a third party laboratory, has greatly increased the turn around time for test results and reporting while reducing the overall cost of these services. We are currently equipped with a walk-in curing room for storing concrete, mortar and grout test samples and also several lime-water submersion tanks if needed. We utilize a Forney, digital readout compression machine to test concrete, mortar and grout samples for their compressive strength. Our concrete laboratory is currently CCRL (Cement and Concrete Reference Laboratory) and our soil laboratory's AMRL (AASHTO Materials Reference Laboratory) are certified. Our in-house laboratory facility's equipment meets the standards of excellence required to generate clear and accurate test results, with faster turnaround time.

Standard and Modified Proctors (with rock corrections)

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.

Standard Test Method for Relative Density (Specific Gravity) and Absorption of Coarse Aggregate

Relative density (specific gravity) is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles – also referred to as the absolute volume of the aggregate.

ASTM D2216-10 Standard Test Methods for Laboratory Determination of Water (Moisture) Content of Soil

For many materials, the water content is one of the most significant index properties used in establishing a correlation between soil behavior and its index properties. The water content of a material is used in expressing the phase relationships of air, water, and solids in a given volume of material.

Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates

his test method is used primarily to determine the grading of materials proposed for use as aggregates or being used as aggregates. The results are used to determine compliance of the particle size distribution with applicable specification requirements and to provide necessary data for control of the production of various aggregate products and mixtures containing aggregates.

ASTM D4318-17e1 Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of Soils

 

These test methods are used as an integral part of several engineering classification systems to characterize the fine-grained fractions of soils and to specify the fine-grained fraction of construction materials. The liquid limit, plastic limit, and plasticity index of soils are also used extensively, either individually or together, with other soil properties to correlate with engineering behavior such as compressibility, hydraulic conductivity (permeability), compactibility, shrink-swell, and shear strength.

Standard Test Methods for Compressive Strength of Molded Soil-Cement Cylinders

Method A makes use of the same compaction equipment and molds commonly available in soil laboratories and used for other soil-cement tests. It is considered that Method A gives a relative measure of strength rather than a rigorous determination of compressive strength.

ASTM D3080 / D3080M Standard Test Method for Direct Shear Test of Soils

This test method covers the determination of the consolidated drained shear strength of a soil material in direct shear. The test is performed by deforming a specimen at a controlled strain rate on or near a single shear plane determined by the configuration of the apparatus.

Standard Test Methods for Thickness and Density of Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members

These test methods cover procedures for determining thickness and density of sprayed fire-resistive material (SFRM) used in structural assemblies. These include sprayed fiber and cementitious types.
