What Is Specific Gravity of Aggregate? Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
Specific Gravity of Cover Aggregate: The bulk specific gravity of the cover aggregate will affect the quantity of aggregate needed. The higher the specific gravity the more aggregate is needed and vice versa. Aggregate Wastage: In all chip seals an excess of cover aggregate has to be applied to offset the unevenness of spread and whip-off by ...

The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below) As specific gravity is just a comparison, it can be applied across any units. ...
1. objective. Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity.
