Laboratory Services

Geotechnical Laboratories: Our in-house geotechnical laboratories (Sandy and St. George) are fully equipped to conduct laboratory testing of soils for:

  • Classification (gradation and Atterberg limits)
  • Strength (unconfined, direct shear, and triaxial shear)
  • Natural density and moisture content
  • Consolidation
  • Specific gravity
  • Permeability (rigid-wall and triaxial)
  • California Bearing Ratio (CBR)
  • Gradient ratio
  • Sulfate soundness
  • Resistivity
  • pH
  • Water soluble sulfates
  • Porosity

AGEC laboratories are approved by and/or follow guidelines of these agencies: American Association of State Highway and Transportation Officials (AASHTO: Soils, Concrete, Concrete Aggregate, Hot-mix Asphalt, and Hot-mix Asphalt Aggregate), ASTM, Cement and Concrete Reference Laboratory (CCRL), Western Alliance for Quality Transportation Construction (WAQTC), Utah DOT, and Utah DFCM.

   

Construction Materials Laboratories: Our construction-materials laboratories (Sandy and St. George) have numerous capabilities including:

  • Measuring the compressive and flexible strengths of structural concrete
  • Compressive strength of structural masonry (mortar, grout, brick, block, and composite prisms)
  • Moisture-density relationships (Proctors)
  • Relative density
  • Gradations
  • Asphaltic concrete samples can be analyzed for oil content, grain size distribution, Marshall stability and flow, and bulk specific gravity.
