Soil Field Testing: Physical Properties of Soil

Soil is a natural material and is sometimes employed as a construction material without modification. It is crucial to understand how it performs in its original (in-situ) environment. For this article, we will examine various field tests of soil and the equipment required to perform them.

Soil Sampling & Visual Classification, Methods & Procedures

Performing geotechnical and engineering tests on soils in the field is a combination of necessity and practicality. In this two-part series, this first post looks at methods, procedures, and equipment needed for field sampling and visual classification of soils.

Soil Sample Preparation: Saving Money in Your Geotechnical Lab

With a little thought and planning, you can avoid duplicating the equipment needed to perform many sample preparation tasks. Many ASTM and AASHTO soil tests performed follow similar techniques and use the same or similar equipment to set up samples for your soil testing.

Triaxial Shear Testing of Soils, Understanding Methods and Equipment

Triaxial Shear Testing of Soil

This month's blog discusses the triaxial shear test of soil. It focuses on three different test methods, all with variable requirements based on soil types and properties of individual specimens.

California Bearing Ratio Test: CBR Values & Why They Matter

In this blog post we discuss why it is important to perform strength tests of soil subgrades for pavement design, and also review what is needed for each type of test method whether it be in the lab or out in the field including the DCP test.

Soil Hydrometer Testing: Sedimentation Method Techniques & Equipment

Measuring the particle size distribution of fine-grained soils like clay and silt is best performed using the soil hydrometer test. In this blog post, we provide some guidance from sample prepping to performing the test procedure by following the ASTM D7928 standard test method.

Soil Permeability Test: All You Need To Know

Permeability of Soil: All You Need to Know

In this blog, we briefly discuss what soil permeability (hydraulic conductivity) is and detail what equipment can be used for a wide array of soil permeability tests.

Gilson Servo Control Load Frames: Comprehensive, Adaptable, Precise

Guide to the Gilson Servo Control Load Frames

Laboratory load frames perform multiple test methods on a variety of soil, asphalt, and cement materials simply by changing prescribed components used for load and distance measurements. This blog post introduces Gilson’s innovative Servo Control Load Frames and explores important considerations for selection of a suitable load frame and testing components for your applications.

Soil Classification: Foundation and Pavement Design Starts Here
Soil Classification: Foundation and Pavement Design Starts Here

In this blog, we explore the two primary forms of soil classification for geotechnical purposes. Visual and laboratory classifications of soils are two distinct procedures that are part of a complete soils investigation.
