Obtaining asphalt binder rheological properties from BBR strength test—the effect of loading rate

Selecting asphalt binders that have good cracking resistance at low temperatures is the first step in designing asphalt mixtures for durable asphalt pavements in cold regions. To evaluate low-temperature cracking resistance of binders, rheological properties (creep stiffness and m-value), and fracture properties (failure stress and strain) are required. Recently, a new strength test was developed to measure the fracture properties of binders...
