Product Information
The bending beam rheometer is used to test the low-temperature bending creep stiffness of asphalt binder according to current specifications and SHRP methods. Used to evaluate the low-temperature fracture characteristics of asphalt binder. The test results include indicators of low-temperature creep stiffness S (t) and creep stiffness change rate m (t). Using Peltier technology/compressor to cool the temperature from room temperature to -40 ° C, using magnetic stirring, the temperature control accuracy is within 0.1 ° C. The instrument can measure the deformation accuracy of the specimen up to 0.155 microns, and the loading force accuracy can reach 0.147 millinewtons (0.015 grams). The load range is continuously adjustable from 0-450 grams. RS-232/IP/U communication is used between the computer and BBR to control the BBR, and the software can generate test reports.
