AASHTO T 335-09 (2018) is a standard method of test that focuses on determining the percentage of fracture in coarse aggregate. The test method provides guidance on assessing the mass percentage of fractured particles within a sample of coarse aggregate. The standard specifies certain requirements that the fractured particles must meet in order to be considered in the calculation of the percentage of fracture.

The purpose of this test is to evaluate the quality of a coarse aggregate by quantifying the amount of fractured particles present. Fractured particles in the coarse aggregate can affect the performance of concrete and other construction materials. By determining the percentage of fracture, engineers and contractors can make informed decisions about the suitability of the coarse aggregate for specific applications.

The test method is conducted by taking a representative sample of the coarse aggregate and subjecting it to a series of sieving and weighing procedures. The fractured particles meeting the specified requirements are identified and weighed, and the percentage of fracture is calculated based on these weights. This test method provides a standardized and reliable approach to evaluate the percentage of fracture in coarse aggregate, ensuring consistency and accuracy in assessment.
