(be the first to review)

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. The BBR test method is applicable to unaged asphalt or asphalt aged using aging procedures such as rolling thin film oven or pressure aging vessel.

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;
