DETERMINING THE PERCENTAGE OF FRACTURE IN AASHTO T 255. c. Reduce the sample using Method A Mechanical Splitter, in accordance with the FOP for AASHTO T 248, to the appropriate test size. This test size should be slightly larger than shown in Table 1, to account for loss of fines through washing if necessary. TABLE 1 Sample Size Method 1 (Combined Sieve Fracture) Nominal Maximum Size*

fracture toughness of the eyebar was extremely low, a relatively small crack led to a brittle fracture of the eyebar, which in turn led to the collapse of the bridge. This collapse was the catalyst for many changes in mate-rial specifications, design, fabrication and shop inspection of steel bridges. These requirements are codified in the AASHTO

The decision to define members aFCMss has often been made
