Friction angle of crushed rock
The angle of internal friction of a crushed stone will be directly influenced by type of rock and grain size. Forty-one (41) seems to me possible, but dangerous. I would use a safe 36 degrees unless a direct shear test is performed on a sample. There's at-rest earth pressure and active earth pressure.

Compacting AASHTO #57
I do not believe it is referred to as 'AASHTO 57 stone', however, #57 stone as defined by quarries, state agencies, etc. is an aggregate blend of size 5, 6, & 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using stone as a …

Density of Aggregate
The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3).

Gravel Calculator
To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. The volume formula for a rectangular (or square) box in cubic feet is height (ft) x width (ft) x length (ft), as seen in the figure below: For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft ...

Density of Construction Materials in kg/m3 and lb/ft3
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.

Density of Rocks and Soils
What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3.
