AASHTO R 49-09 (2018) is a standard practice that focuses on determining the low-temperature performance grade (PG) of asphalt binders. This is achieved by analyzing data obtained from the bending beam rheometer (T 313) and the direct tension tester (T 314). The standard outlines that the practice can be used for both unaged asphalt binder material or material that has been aged using methods such as T 240 (RTFOT), R 28 (PAV), or T 240 (RTFOT) combined with R 28 (PAV).
The temperature range for analysis is specified as being from +6°C to -36°C. Furthermore, the standard mentions that the software TSAR™, which is available from Abatech Inc., can be utilized for the required calculations.
