such as the gravels, had a smaller volume of voids than the more angular crushed stone. In some instances, the difference in the percent voids produced by a change in shape of the aggre­ gate was quite large. Regardless of the shape of the aggregate, the smaller aggregates had greater percent voids than the larger aggregates.

bulk density and percentage voids of aggregates

Density is usually shown as a percent of maximum theoretical (Gmm) or the specific gravity of the in-place compacted density divided by the Gmm. Air voids is used interchangeably with density and is calculated: percent air voids = 100 – percent density. Density is achieved by compaction of the paver-laid asphalt-aggregate mixture.

2 天前  The 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.

How Much Void in RipRap - Foundation engineering -

2005-11-1  I assume (I hate using that word, but that is what brings me to write this question in the first place..) that there is 20-33% voids in the same volume that "stacked" riprap is placed. If there is 20% that amounts to 120 pcf for the minimum specified scenario. A 90 pcf volume amounts to 40% voids.
