  • Full Compliance Testing of Aggregate for use in Asphalt Designs
  • Performance Grade (PG) Testing of Binder for use in Asphalt Designs
  • All types of Asphalt Designs
  • Slurry Designs
  • Modified Lottman (Durability)
  • Air Perm @ 7% Voids
  • Gyratory (Workability)
  • Hamburg Wheel Tracking
  • Dynamic Creep
  • MMLS
  • Stability & Flow
  • ITS
  • Immersion Index
  • Binder Content & Grading
  • MVD (Rice)
  • Schellenberg Drainage
  • Cantabro Abrasion
  • Falling Head Water Permeability
