Conventional Asphalt Testing

  • Sampling
  • Binder content
  • Particle size distribution
  • Gross density
  • Spatial density
  • Volumetric characteristics: degree of compaction, void content, fictive void content, void filling degree, binder volume
  • Marshall compaction
  • Water sensitivity
  • Resistance to chemical thawing agents
  • Grain loss of test specimens from open-pored asphalt
  • Expiry test
  • Water permeability
  • Penetration depth of mastic asphalt cubes

Performance Checks

  • Test specimen production: Asphalt mix production by means of forced mixer, roller sector compactor, Marshall compactor
  • Deformation properties: Tracking test, splitting tensile strength, splitting tensile swelling test, dynamic punch penetration test, compression swelling test
  • Stiffness and fatigue properties: Splitting tensile test, splitting tensile test, 4-point bending test, 3-point bending test
  • Cold properties: Uniaxial tensile test, cooling test, relaxation/retardation behavior
  • Layered bond: dynamic layer bond testing, static layer bond testing
  • Surface properties: Skid Resistance pendulum device with discharge meter
  • Wehner-Schulze Test Bench / Friction-After-Polishing
