A.A.R. Testing Laboratory, Inc. has been at the forefront

of the inspection and testing industry since its founding in 1989


The best field inspection personnel cannot be effective without excellent support from the laboratory. A.A.R. Testing maintains a state of the art construction material testing laboratory, complete with a climate controlled specimen storage area, two specimen break machines as well as other complex testing and diagnostic equipment. Concrete and masonry specimens, soil, asphalt, fire resistive materials and many other material types are tested in house.

Our laboratory technicians have extensive knowledge of codes and standards commonly used throughout the industry—from American Society for Testing and Materials (ASTM), American Association of State Highway and Transportation Officials (AASHTO), Washington State Department of Transportation (WSDOT), United States Army Corps of Engineers (USACE) and many others.

Selected Laboratory Testing Capabilities:

  • Concrete Test Cylinders
  • Concrete Flex-Strength Specimens
  • Grout Cube Specimens
  • Shotcrete Cores
  • Masonry Test Prisms
  • Moisture, Specific Gravity
  • Proctors
  • Sieve Analysis
  • Sand Equivalent
  • Plasticity Index
  • Hydrometer
  • Cleanness Value
  • Rice Density Test
  • L.A. Abrasion

In addition to testing materials for normal construction activities, A.A.R. participates in two national construction material proficiency testing programs and administered by the Cement and Concrete Reference Laboratory (CCRL) and AASHTO Materials Reference Laboratory (AMRL). Involvement with these programs ensures global accuracy of specimen testing and consistency not only within our own lab but across the industry.

Reliable and precise results are further ensured by making use of the highest quality supplies and test equipment available. Our lab personnel keep meticulous maintenance and calibration records for each piece of laboratory equipment and track consumable supplies to guarantee its quality and zero variance from advertised function.
