Asphalt, Bitumen | Measurement of bitumen according to ASTM D4402 / AASHTO T316
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.
