Bulk density of aggregate is the mass or weight of the aggregate that is required to fill a container of a specified unit volume. The percentage of space or voids between the individual particles and in a unit volume of the aggregate mass is known as a void percentage.
Gravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about 0.25, while gravel with silt can have a void ratio of 0.2 or less.

Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.
