1.1 ,This practice covers the calculation of low-temperature properties of asphalt binders using data from the bending beam rheometer (see Test Method D6648) (BBR) and the direct tension tester (see Test Method D6723) (DTT). It can be used on data from unaged material or from material aged using Test Method D2872 (RTFOT), Practice D6521 (PAV), or Test Method D2872 (RTFOT) and Practice D6521 (PAV). It can be used on data generated within the temperature range from +6 ,°,C to –,36 ,°,C. This practice generates data suitable for use in binder specifications such as Specification D6373.
