Elongated particles with an aspect ratio of greater than 1 to 3 should be no more than 5 % of all aggregate particles by weight. A typical gradation for a paving course 25 mm thick is: Sieve Size Percent Passing inches mm 3/4 19.0 100 1/2 12.5 95-100 3/8 9.5 80-95 No. 4 4.75 58-75 No. 30 .0006 20-35 No.
