James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 5.9.5 Bulk Specific Gravity. The bulk specific gravity is the ratio of the weight of a given volume of aggregate, including the permeable and impermeable voids in the particles, to the weight of an equal volume of water (Kandhal et al., 2000; Prowell and Baker, 2004; Sholar et al., 2005).

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.

The bulk density or unit weight is the weight per unit volume (mass per unit volume or density). Voids in unit volume of aggregate are the space between particles in an aggregate mass not occupied by solid minerals. The bulk density values determined based on this test can be used for many methods of selecting proportions for concrete mixtures.

Note that original units were lb/ft 3, so actual number of significant places in kg/m 3 column are the same as the original unit, i.e., Aluminum density is really only known to three significant places even though four are presented.

D. bulk; however, the more porous aggregates demand more asphalt in paving mixtures; and the higher asphalt content adds somewhat to the unit weight of mixture. Summarily, the constituent-mineral gravities provided a basis for classification and areal differentiation--that is, grouping and averaging 0. D. bulk gravity and absorption data.

There is no specification for bulk specific gravity, but it is used to calculate other specified parameters such as air voids, VMA and VFA. Typical Values. Typical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction.

Contractor using cold-mix asphalt for patching pothole. Bulk asphalt cost per truckload. A bulk truckload of asphalt costs $500 to $1,800, including delivery fees. Tandem trucks carry 13 to 20 tons of asphalt that cover 550 to 850 square feet with a layer 3 to 5 inches thick. Prices vary according to the asphalt-delivery distance.

Density can be defined as the unit weight of the asphalt concrete acheived through the compaction process. Hence, the objective of compaction is to produce a dense mass with high unit weight. Again, the choice is between achieving a high density at the time of construction by means of construction equipment, or to allow traffic to develop the ...

Typical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction. Beside above, how do you calculate apparent specific gravity? Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of ...

Answer (1 of 4): As a general rule for estimating purposes, it is usually around 140 to 145 pounds per cubic foot for most of the designs I've seen in the US. The actual unit weight may vary a little. This is assumed to be compacted. You determine how much you need by taking the area that you ...

5.1 The results obtained from this test method can be used to determine the unit weight of compacted dense asphalt mixtures and in conjunction with Test Method D3203/D3203M, to obtain percent air voids.These values in turn may be used in determining the relative degree of compaction.

1.3 The bulk specific gravity of the compacted asphalt mixtures may be used in calculating the unit weight of the mixture. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).
