Dynamic Shear Rheometers (DSR) performs the critical rheological characterization analysis required for Performance Grade (PG) classification of asphalt binders. The lower plate is fixed while the upper plate oscillates back and forth across the sample to create a shearing action. The DSR test uses a thin asphalt binder sample sandwiched between two circular plates.

Performance Grade (PG) determination test.

Determination of complex shear modulus G* and phase angle δ of road bitumen at different temperatures.

Determination of deformation properties of bitumen with Multiple Stress Creep Recovery test (MSCR – Test).

Reliable and long lasting — sturdy stainless steel construction

Simple to use with intuitive software guiding the user through the various test phases

Affordable, robust and accurate, the new DSR offers the following benefits:

Great value — ideal for asphalt and bitumen laboratories at very competitive.

Robust with excellent temperature stability and accuracy.
