Petrochemicals | Measurement of bitumen and asphalt binders with ViscoQC 300

Viscosity is an important parameter for bitumen and asphalt binders to ensure proper handling, mixing and application. This application report shows how a quality control test according to ASTM D4402 and AASHTO T316 (max. +175 °C) is performed with ViscoQC 300.


The viscosity of asphalt binders and bitumen at elevated temperatures influences the:

  • Pumpability: The asphalt binder must be able to be pumped between different plants and storage containers.
  • Mixability: The bitumen must be able to be properly mixed with additives and fillers during the production.
  • Workability: The hot mix asphalt (HMA) must be able to be placed and compacted with reasonable effort.
