Bending Beam Rheometer DW5325

Bending Beam Rheometer DW5320 Description

DW5325 Bending Beam Rheometer is used for determining the flexural creep stiffness of asphalt, so as to evaluate the low-temperature cracking performance of asphalt binder.

Follows are features of the machine:

• The instrument mainly consists of a loading system with specimen support, a controlled-temperature liquid bath and a computer-controlled data acquisition system;
• A prismatic test specimen is placed in the controlled-temperature liquid bath and subjected to a constant test load (980±50)mN applied to its mid-point for 240s;

• It’s equipped with air bearing loading mechanism to apply specified load to the specimen and high precision displacement sensor to measure the deflection of the specimen;
• Full automatic test: Touch screen control, microcomputer display load, displacement and liquid bath temperature, easy to set the parameters, in the test process real-time display load, displacement and liquid bath temperature curve;
• Test results including stiffness and m-value can be obtained through professional software automatically;

• Beautiful in design and durable: Adopt stainless steel loading shaft and stainless steel specimen support. The main machine table adopts 2mm thick stainless steel material. The lining is 5mm thick tetrafluoroethylene material with effective heat insulation and good corrosion resistance.
