The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping.
Calculating appropriate volume is critical to accuracy. In-bank soil, loose soil that has been excavated and fill soil that has been compacted, have different material densities and resulting load factors.

Bulk density, particle density, and porosity are three soil physical properties exemplifying the relationships among the soil phases. The volume of voids in soil is related to the percentages of sand, silt and clay (soil texture) and to the arrangement of these soil particles soil structure.
Most previous studies have focused on the small-strain shear modulus (Gmax) of clean sand or sand-silt/clay mixtures, while little attention has been given to sand-gravel mixtures which are extensively used in many construction projects, such as railway foundation, rockfill dam and artificial slope. This study investigates the effect of …

Soil or rock from the borrow expands when dropped on the lorry or the landfill - or stockpiled. One cubic from the borrow does not translate to one cubic dump.
Medium textured soils with a blend of silt, clay and sand particles and good aggregation provide a large number of pores that hold water against gravity. Coarse soils are dominated by sand and have very little silt and clay. Because of this, there is little aggregation and few small pores that will hold water against gravity.
3.2 Effective Porosity In groundwater assessments, it is the interconnected pore volume occupied by flowing groundwater that is of most interest.
Bulk density of a soil is the mass per unit volume including the pore space. Bulk density increases with clay content and is considered a measure of the compactness of the soil. The greater the bulk density, the more compact the soil. Compact soils have low permeability, inhibiting the movement of water.

The addition of gravel to the clayey soil led to an increase in Maximum Dry Density (MDD) and reduction in Optimum Moisture Content (OMC) as the concentration of gravel increases with size in the ...
The bulk densities are given for sedimentary rocks as well as soils, because sedimentary rocks typically have variable porosity. Bulk density includes both the grains and the interstitial spaces. The grain density is the actual density of the particles, which might be a mineral.
5. Gravel, Sand, Silt, and Clay. The relative amounts of gravel, sand, and fines; the plasticity characteristics of the fines (silt, clay, or both); and the presence of cobbles and boulders all affect the soil' s use as a construction material. These characteristics also affect selection of laboratory and field tests to be performed on the soil.
Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and …
Chapter 9 SPECIFIC GRAVITY OF SOLIDS IN LATERITE SOILS Specific gravity is the ratio of the mass of a given volume of material to the mass of an equal volume of water at a temperature of 4°C.
