TABLE 11 <br /> Standard Sizes of Coarse Aggregate' <br /> That Meet <br /> Xerxes CRUSHED STONE Spedification' <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 /> Standard Sizes of Coarse Aggregate <br /> Sieve Size 7 78 8 <br /> Amounts finer than each laboratory sieve(Square Openings weight percent <br /> 1 in. — — — <br /> g <br /> P.2 <br /> 4 a r <br /> 3/4 in. 100% 100% — <br /> a <br /> 1/2 in. 90 to 100 90 to 100 100 <br /> 3/8 in. 40 to 70 40 to 75 85 to 100 <br /> No.4(0.187 in.) 0 to 15 5 to 25 10 to 30 <br /> 1/8 in. — — — <br /> P <br /> No.8(0.094 in.) 0 to 5 0 to 5 0 to 5 <br /> NOTES <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 1/s"and 1/z"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 />
