Overview

Principle and Application of Asphalt Mixture Bending Beam Rheometer: To measure the low-temperature creep stiffness of asphalt binder, evaluate the low-temperature crack resistance of asphalt, and focus on reflecting the ability to resist temperature shrinkage cracking

Product Details

The ATS Bending Beam Rheometer (BBR) is designed according to ASTM D6648-01 and AASHTO T313-02 for conducting bending tests on asphalt binders and similar specimens. These tests were initially conducted by the Strategic Highway Research Program (SHRP) in the United States, which applied a constant load to specimens stored in frozen liquid to determine their deformation rates at different temperatures
