AASHTO T 300-11 (2020) PDF Download

AASHTO T 300-11 (2020) is a standard method of testing the force ductility of asphalt materials. The force ductility of a material refers to its ability to withstand tensile stress when pulled apart. In this test, a briquet specimen of the asphalt material is subjected to a pulling force at a specified temperature. The test is typically carried out at a temperature of 4.0 +/- 0.5°C (39.2 ± 1.0°F) and at a pulling speed of 5 cm/min (2 in./min) ± 5.0 percent.

The purpose of this test is to evaluate the force ductility of asphalt materials, particularly polymer-modified emulsions. By measuring the tensile stress induced on the specimen during the test, the test can provide valuable information about the performance and durability of the material. The standard provides specific guidelines for conducting the test, ensuring consistent and accurate results across different laboratories.
