AASHTO T 314-12 (2016) PDF Download

The AASHTO T 314-12 (2016) standard provides a method for determining the failure strain and failure stress of asphalt binders through a direct tension test. This test can be conducted on both unaged and aged asphalt materials, utilizing the T 240 (RTFOT) or R 28 (PAV) procedures.

The test apparatus specified in this standard is designed to accommodate a temperature range of +6 to -36°C, allowing for testing under various temperature conditions. The purpose of this method is to evaluate the fracture properties of asphalt binders, providing valuable information on their performance and behavior during cracking or failure. The results obtained from this test can be used to assess the durability and suitability of asphalt binders for use in pavements and road construction projects.
