Section 902. AGGREGATES General Requirements. The Department may reinspect and retest aggregates regardless of inspection at the producing plant. Provide safe access to the material for sampling from haul units or stockpiles. Do not use spent metal casting foundry sand, unless the contract expressly allows for its use.
Two tests are generally utilized to specify the desired shape of coarse aggregates, the flakiness index and the flat and elon gated test. The flakiness index is generally specified in Europe with a maximum requirement of 25 percent (7, 37). Arizona also has utilized this specification for the flakiness index (7).

aggregate Typical grading limits for these materials are shown in Table 6 2. After crushing, the material should be angular in shape with a Flakiness Index (British Standard 812, Part 105 (1990)) of less than 35 per cent. If the amount of fine aggregate ...

May 10, 2019· Flakiness Index, FI (%) ... Moreover, water absorption values are always greater than the typical values for natural aggregates. More detailed examination reveals that the highest values are achieved by the coarser fraction. Water absorption is an indirect parameter for the porous rate of aggregates. This means that the composition of PRA is ...
