Tests of bituminous binders and emulsions

We perform verifications of modified and unmodified bituminous binders’ properties.

  • Determination of needle penetration ČSN EN 1426
  • Determination of softening point – Ring and ball method ČSN EN 1427
  • Determination of the Fraass breaking point ČSN EN 12593
  • Determination of the tensile properties of modified bitumen by the force ductility method ČSN EN 13589, ČSN EN 13703
  • Determination of the elastic recovery of modified bitumen ČSN EN 13398
  • Determination of storage stability of modified bitumen ČSN EN 13399
  • Determination of the resistance to hardening under influence of heat and air – RTFOT method ČSN EN 12607-1
  • Determination of dynamic viscosity of bituminous binders using a rotating spindle apparatus ČSN EN 13302
  • Visualisation of polymer dispersion in polymer modified bitumen ČSN EN 13632
  • Determination of the pH value of water phase and bituminous emulsion ČSN EN 12850
