The BBR assesses low-temperature properties by measuring the flexural creep stiffness of a bitumen beam specimen at low temperatures. It provides parameters like creep stiffness (S) and m-value (rate of stiffness change), indicating the binder’s ability to resist thermal cracking by absorbing stresses through deformation without fracturing.
