Rock Aggregates and Its SuitabilityThe least angular most rounded aggregates have 33 percent voids and the angularity number of an aggregate is defined as the amount by which the percentage of voids exceeds 33 The angularity number usually ranges from 0 to 12 8 Ten Percent Fines Value This gives a measure of the resistance of the aggregates to crushing.void ratio crushed stone crushed stone voids Earthworkgrading engineering Eng Jul 09 2003 RE crushed stone voids 7 Jul 03 2319 It depends upon the specific gravity of the stone as well as the gradation I use a dry rodded unit weight of 1630 kgm3 and a specific gravity of 268 for the gravels in my location That would equate to a void ratio of about 062 ignoring the pores on the face of the aggregate particles
