Laboratory Equipment

testing fine aggregate angularity

Our AASHTO-accredited NCAT laboratory is well equipped to perform all routine mix design and quality control tests for binders and mixtures, including a full array of Superpave asphalt binder-testing equipment such as

  • dynamic shear rheometers
  • bending beam rheometers
  • pressure aging vessel
  • direct tension tester
  • Brookfield viscometer

In addition to the capability to perform aggregate source and consensus property
testing, the laboratory also includes

  • digital aggregate imaging system
  • Micro-Deval abrasion equipment
  • laser particle-size analyzer
  • British polishing wheel and pendulum tester

NCAT is also equipped to perform an array of advanced characterization mixture tests,
including

  • dynamic modulus
  • confined repeated load deformation
  • Hamburg wheel tracking
  • Asphalt Pavement Analyzer rutting
  • indirect tensile creep compliance and strength
  • repeated-load shear
  • bending beam fatigue
  • fracture energy
  • hydraulic conductivity
  • interlayer bond strength
