reduces the impact of aggregate size and gradation on test results. The median of the specification gradation should be normalized for the aggregate products as shown in Table 1, and should be used for this test.

the strength of aggregates are the direct shear (DS) and triaxial (TX) tests, with DS being the simplest and most regularly used test. Based on the American Association of Testing Materials (ASTM) standards, the maximum particle sizes for DS and TX testing are 1/10th and 1/6th of the width or diameter of the device, respectively.
