AASHTO TP 127-17 (2021) PDF Download

The AASHTO TP 127-17 (2021) standard provides a method for determining the fracture energy density of asphalt binder using the Binder Fracture Energy (BFE) test. This test is used to evaluate the cracking performance of asphalt binder and is typically conducted on asphalt binder aged using the Rolling Thin Film Oven (RTFO) and Pressure Aging Vessel (PAV) procedures. However, it can also be used for any type of binder, including neat or modified binders, as well as asphalt binder extracted and recovered from pavement.

The test involves subjecting the asphalt binder to direct tension, measuring the energy required to fracture the binder, and calculating the fracture energy density. The test apparatus is designed to be used within an intermediate temperature range of 0°C to 25°C.

This standard provides a standardized procedure for conducting the BFE test, ensuring consistency and accuracy in determining the fracture energy density of asphalt binder. The results obtained from this test can be used to assess the cracking performance of different types of asphalt binders and aid in the selection and design of asphalt mixtures for improved pavement performance.
