B085-07N Dynamic Shear Rheometer (DSR)

1、 Product Usage:

Dynamic shear rheometerDSRUsed to measure the rheological properties of asphalt binder at high temperatures(Complex shear modulus, phase angle, etc).SHRPDynamic shear rheometer（DSR）It is to determine whether aged or unaged asphalt,(Modified or unmodified asphalt)5-85An essential instrument for measuring the viscoelastic properties within the temperature range of ℃. pressAASHTO MP1During the method test, the asphalt sample is clamped in a circular parallel plate at a specified temperature, and the complex shear modulus and phase angle of the sample are measured by applying a known torque. Two modes of testing can be conducted using the corresponding software: strain control (measuring its stress) and stress control (measuring its strain); can be performedAASHTO PP6Temperature scanning test. The corresponding software can be used for frequency scanning tests, and general systems can be used for non frequency scanning testsSHRPExperiment, used for research purposes.

2、 Product features:

The rheometer provides a traditional asphalt immersion unit and a dry asphalt temperature control attachment. Both temperature control systems comply withSHRPTheASTMandAASHTOStandard requirements, including8mmand25mmParallel plates, sample molds. The dry asphalt system will have an excellent upper heating plate system（UHP）And unique staircase stylePeltierPerfect combination of boards. Automatic zero heat flow calibration with accurate insulation gradient less than+/- 0.1℃. This dry asphalt system features intelligent temperature control with a brand new patented design（ATC）, making this dry asphalt system the only step type that can directly control the temperature of the upper and lower fixtures simultaneouslyPeltierSystem. Flexible cooling methods include external circulators or new eddy current cooling.
