0 1 0 <br />TABLE I <br />i - i • . - <br />SpecificationThat Meet <br />Xerxes PEA GRAVEL <br />This table identifies standard sizes of coarse aggregate that meet Xerxes' pea gravel <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 6 as an example, we can expect 20% to 55% of the sample <br />(measured by weight) to pass through a'/2 inch sieve. <br />NOTES <br />1. Standard sizes of coarse aggregate per ASTM D-448, ASTM C-33 and AASHTO M 43. <br />2. PEA GRAVEL (mix of rounded particles) must have a minimum diameter of 1/8' and a maximum <br />diameter of 3/4'. No more than 5% of the backfill shall pass through a No. 8 sieve. <br />
