AASHTO T 334-08 (2020) is a standard method used to estimate the cracking tendency of concrete. This test specifically focuses on the effects of different concrete properties on the time-to-cracking of concrete specimens when restrained. It is important to note that this standard is not designed to determine the time of initial cracking in a specific structural application, but rather serves as a comparative measure for concrete properties.

The purpose of this standard is to provide a consistent and reliable method for evaluating the cracking potential of concrete. By subjecting restrained concrete specimens to specific conditions, the test enables researchers and practitioners to assess how variations in concrete properties can influence crack formation.

The standard outlines a procedure that allows for the accurate estimation of the cracking tendency of concrete. It provides guidance on the preparation and testing of the concrete specimens, as well as the necessary equipment and measurement techniques.
