5.2 This test method may be used to determine the density and unit weight of compacted soils used in construction of earth embankments, road fill, and structural backfill. This test method often is used as a basis of acceptance for soils compacted to a specified density or a percentage of maximum ...
• γ s is the saturated unit weight of the material • γ w is the unit weight of water If we assume we have a well compacted fill at 13% moisture with density of 132 pcf, the dry unit weight would be 132/(1+0.13) = 117 pcf.
Cubic Yard Calculator. We sell all of our online materials by the cubic yard. A cubic yard is equal to 27 cubic feet. You can use the online calculator to determine how many cubic yards of material are required. As a general guide, 1 cubic yard of aggregate, sand, or dirt is equivalent to 1.5 tons.
Typical Soil Properties Bulk Unit Weight (γ) This is typically 15 kN/m3 for many top soils but can vary between 11 kN/m3 for a loose dry soil to 18 kN/m3 for dense wet soils. Figure 1 shows a range of typically recorded values. Cohesion (c)

Flowable Fill is an earthlike material to be used as soil replacement, it is self compacting and has a flowable consistency. Typical uses include: utility trench backfill, mud jacking, erosion control, pipe bedding, subbase stabilization, sinkhole fills, construction mud mats, abandoned tank fills, and more.

Foundation soil — a cohesion of zero and a unit weight of 125 lbs. Anchor: #WTETNBOO Select fill - a cohesion of zero, a friction angle of 34 degrees, and a unit weight of 105 pcf or 125 pcf depending on the stability analysis being conducted.
2. Determine the net weight of water in the measure to an accuracy of ± 0.1 %. 3. Measure the temperature of the water and determine its unit weight from Table 2, interpolating if necessary. 4. Calculate the Factor, F, for the measure by dividing the unit weight of the water by the weight required to fill the measure. TABLE 2 Unit Weight of Water
Soil unit weight, as referred to as Specific weight, is the weight per unit volume of soil. It may refer to - Wet unit weight: Unit weight of the soil when the pore are fully or partially filled with water. - Dry unit weight: Unit weight of the soil the pores are filled only with air without any water. Gamma_d = Gamma / …
ND T 191 – DENSITY OF SOIL IN-PLACE BY THE SAND CONE METHOD . ... fill the funnel with sand. 2. Open the valve and keep the funnel at least half full with sand during filling. ... ASTM D 2167 - DENSITY AND UNIT WEIGHT OF SOIL IN PLACE BY THE RUBBER-BALLOON METHOD Author:
Moisture in soil holds it together and is a primary factor in determining the average weight of a cubic yard of soil, no matter what components the soil is made of. For instance, 1 cubic yard of dry soil topsoil weighs about 2,000 pounds, while the same soil can weigh around 3,000 pounds when saturated.
CIP 17 - Flowable Fill Materials WHAT is Flowable Fill? ... pacity similar to well-compacted soil. WHY is Flowable Fill Used? How is Flowable Fill Ordered? 1989 AND 2000 ... • Unit weight, yield and air content of flowable fill are measured by ASTM D 6023.

The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma ). A commonly used value is the specific weight of water on Earth at 4°C which is 9.807 kN/m 3 or 62.43 lbf /ft 3 .
Stress in the ground. Total stress; Pore pressure; Effective stress; ... soil, water, and surface loading. Total stresses are calculated from the unit weight of the soil. Unit weight ranges are: dry soil: g d: ... rolled fill 18kN/m³, assume water = 10 kN/m³.
What Is the Weight of 1 Cubic Yard of Topsoil? One cubic yard of topsoil weighs approximately 1,080 pounds. This estimate is based on the calculation that 1 cubic yard equals 27 cubic feet. One cubic foot of topsoil weighs approximately 40 pounds. These weights are estimations based on available ...
The soil borrow material to be used to construct a highway embankment has a mass unit weight 96.0 lb per cu ft (pcf) and water content of 8%, and specific gravity of soil solids is 2.66. The specifications require that the soil be compacted to dry unit weight of 112 pcf and that the water content be held to 13%. CHAPTER 4b.
SOIL COMPACTION Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. ... moisture content and dry unit weight for saturated soil is shown on the graph in Figure 3. This line is known as the zero air voids line. Moisture content
Where γ is the total unit weight of the soil and γ' is the effective (or submerged) unit weight of the soil which equals the total unit weight of soil minus the unit weight of water (i.e. 62.4 pcf). Thus: σv' = 5(120) + 5(120-62.4) = 888 psf Calculating the Lateral Earth Pressure
The moist compacted unit weight was determined by rodding each layer by 25 strokes of tamper rod of 5/8" diameter, with each layer filled up to approximately one third (1/3) of the measure height and the process continued until the measure is completely filled.
In-place Densities of Earth Fill ASTM D1556: Standard Test Method for Density and Unit Weight of Soil in Place by Sand-Cone Method. ASTM D2167: Standard Test Method for Density and Unit Weight of Soil in Place by the Rubber Balloon Method. ASTM D2937: Standard Test Method for Density of Soil in Place by the Drive-Cylinder Method.
the effective unit weight of the soil where: γ' = γ s – γ w γ' = effective unit weight of soil γ s = total unit weight of soil and γ w = unit weight of water The submerged weight can be estimated as about half of the total weight of many granular soils. The angle of internal friction (φ) is not appreciably changed by submergence.
Densities of Soil. The terms density and unit weight are used interchangeably in soil mechanics. Though not critical, it is important that we know it. To find the formula for density, divide the formula of unit weight by gravitational constant g (acceleration due to gravity).
Multiply the volume by weight density to obtain the weight of the sand in pounds (See Reference 1). Assume the sand is dry for the example. Completing the exercise leads to 1.4 cubic feet times 100 lb per cubic foot, or a weight of 140 lbs.
