r_Z3 <br />�j <br />TABLE 11 <br />Standard of <br />Coarse Aggregate' <br />That <br />Xerxes CRUSHED STONE Specification <br />This table identifies standard sizes of coarse aggregate that meet Xerxes' crushed stone <br />specification. The first column identifies standard sieve sizes that are used to grade aggregate <br />material. The remainder of the columns have a standard aggregate size number at the top of <br />the column. For each aggregate size, the amount of material finer than each laboratory sieve <br />(square openings) is given as percentage of the total weight of the sample. These percentages <br />give an indication of the particle size distribution or gradation within a given aggregate size. <br />Using aggregate size number 7 as an example, we can expect 0% to 15% of the sample <br />(measured by weight) to pass through a No. 4 sieve. <br />1. Standard sizes of coarse aggregate per ASTM D-448, ASTM C-33 and AASHTO M 43. <br />2. STONE CRUSHINGS should be washed and free flowing. The mix of angular particle size <br />should be between/s" and 1/2" and must meet ASTM C-33 paragraph 9.1 requirements. No more <br />than 5% of the backfill shall pass through a No. 8 sieve. <br />
