Concrete
In the field, freshly poured concrete is tested to make sure that it meets specifications for air content, slump and temperature. At the time of testing, we cast specimens to test for strength that are then sent to a laboratory to determine the compressive and flexural strength of the concrete.
Soils & Aggregates
We will help you to determine if the soils and aggregates for your project are being used to their full potential. Field testing includes in-place density testing, shear strength testing, bearing capacity and more. In coordination with the laboratory, further testing can be conducted to examine soil and aggregate properties. Some common examples include proctors, gradations, classification, degradation, moisture content and specific gravity.
Asphalts
Asphalt testing services include roll pattern determination at the time of placement and density testing after placement by use of nuclear density gauge or cores. Furthermore, laboratory testing can be conducted which can include extraction, gradation, mix design using both gyratory and Marshall methods, angularity, bitumen content, specific gravity, and core density
*GLEG does not do it’s own lab testing but will coordinate with a local laboratory when specific tests are needed.
