AASHTO T 368-17 PDF Download

AASHTO T 368-17 is a standard method for measuring the low-temperature flexural creep stiffness of bituminous sealants and fillers using the Bending Beam Rheometer (BBR). This standard applies specifically to bituminous sealants used in the construction and maintenance of roadways.

The purpose of this method is to determine the flexural stiffness of the bituminous sealant, which is important for evaluating its performance at low temperatures. The test can be performed on both unaged materials and materials that have been aged using TP 86, which is another standard method for accelerated aging of bituminous materials.

The test is conducted using a Bending Beam Rheometer apparatus, which is designed to evaluate the material's behavior within the temperature range of -4°C to -40°C. The apparatus simulates the conditions that the sealant may experience during cold weather, allowing for an assessment of its resistance to flexural creep.
