Materials Testing Laboratory

GEC’s testing laboratory has achieved a number of certifications and accreditations. GEC has the only testing laboratory in the Middle Georgia area that meets the stringent requirements of ASTM E329. ASTM E329 (Standard Specification for agencies Engaged in the Testing and/or Inspection of Materials Used in Construction) is a lengthy document that details the qualifications for an inspection agency and laboratory personnel. It also specifies the technical requirements for equipment and procedures used in testing and inspection of construction materials.

Our in-house laboratory can perform a variety of soil, concrete, and aggregate tests. Examples include:

Soil Testing and Analysis

Aggregates

  • Standard or Modified Proctor
  • Grain-size Wash 200
  • Hydrometer
  • Unit weight
  • Specific gravity
  • Soil Moisture
  • Hydraulic conductivity
  • Unconfined compressive strength
  • California Bearing Ratio
  • Pasticity index
  • Constant Head Permeability
  • Particle Size Analysis
  • Specific gravity
  • Hygroscopic Moisture
  • Angularity
  • Hardness
  • Unit Weight
  • Absorption

 

Asphalt & Concrete

  • Concrete Mix Design & Verification
  • Concrete Compressive & Flexural Strength
  • Swiss Hammer or Windsor Probe testing
  • Concrete or Ashpalt coring
  • Asphalt Absorption
  • Asphalt Mix design & verification
  • Asphalt bulk density
  • Marshall Stability & Flow
  • Asphalt Specific Gravity
 

GEC's in-house testing lab has achieved accreditation or certification by several agencies:

 

GEC engineering technicians also participate in a number of qualifications programs. These include:

 

All of our technicians are required to be certified in one of more of the above organizations.

What is ASTM E329? It refers to a document created by the American Society for Testing and Materials (ASTM) that specifies the standards, equipment, and procedures that should be used by a qualified testing agency. The American Association of State Highway and Transportation Officials (AASHTO) is the primary accrediting agency for construction testing labs. They visit the lab and scrutinize every procedure and piece of equipment. If the lab is indeed "up to snuff", it is designated as AASHTO R18 Accredited, and listed at www.amrl.net. GEC's materials testing lab meets these stringent requirements, and is the only Middle Georgia lab that does.

The AASHTO inspection pulls together several accrediting agencies that deal with policies and procedures for testing construction materials. These organizations include:
