Perhaps on reflection 2.1/2.2 t/M3 should be 2.2/2.3 t/M3. Had another OMC/MDD done and the MDD of 2.4 is now 2.2, so I'm going back to 2.1/2.2 t/M3 compacted density in the layer. Remarkably I've had 244 hits on my site for type 1 subbase density and 691 for type one subbase, and that's not all the search variants such as subbase tonnes M3.
To calculate the weight of material needed for a project you will need to know the compacted density of the material. Density is the weight of material per volume. For example pounds per cubic foot. The density of asphalt pavement mixtures does vary depending on mix proportions and the type of aggregate.

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 volume of a relatively undisturbed soil sample obtained from a brass ring.Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.
Unit Weight and Specific Gravity – fill materials can vary in unit weight over a fairly wide range, depending on the type of material and its moisture content. Fill materials that are relatively low in unit weight offer the advantage of transmitting less dead load to …
Density of Clay, compacted lb ft3 = 108.9992192076 lb/ft³ See density of Clay, compacted in hundreds of units of density measurement grouped by weight . Clay, compacted density values, grouped by weight and shown as value of density, unit of density
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.
PDF | The unit weight of municipal solid waste (MSW) is an important parameter in engineering analyses of landfill performance, but significant uncertainty currently exists regarding its value. A ...

Calculate dry unit weight of compaction in the field using the following relation: (1) Here, is the moist unit weight of compacted soil and w is the moisture content of moist soil.
The soil type - that is, grain-size distributions, shape of the soil grains, specific gravity of soil solids, and amount and type of clay minerals, present - has a great influence on the maximum dry unit weight and optimum moisture content. It also has a great influence on how the materials should be compacted …
Equivalent dry unit weight is determined based on the moisture content and the unit weight of compacted soil. A curve of dry unit weight versus moisture content is plotted (Figure 5-4) and the maximum ordinate on this curve is referred to as the maximum dry unit weight ((γ d) max).
instructed to achieve a compacted field dry unit weight of 90 to 95% of the maximum dry unit weight determined in the laboratory by either the standard or modified Proctor test. This is a specification for relative compaction, which can be expressed as Relative compaction .
Feb 29, 2016· 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 ne...
a soil is defined as the weight per unit volume.The typical composition of a soil, subdivided into the three basic soil phases—solid, liquid (water), and gas (air)—is shown in Figure 1.Various relationships and engineering properties are derived from these soil phases, for example, density, unit
To assess the degree of compaction it is important to use the dry unit weight, ... specify that the soil must be compacted to some pre-determined dry unit weight. This specification is usually that a certain percentage of the maximum dry density, as found from a laboratory test (Standard or …
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. GEOTECHNICAL MATERIALS & COMPACTION ENCE 420 ©Assakkaf Slide No. 77
Clay, compacted weighs 1.746 gram per cubic centimeter or 1 746 kilogram per cubic meter, i.e. density of clay, compacted is equal to 1 746 kg/m³. In Imperial or US customary measurement system, the density is equal to 109 pound per cubic foot [lb/ft³], or 1.009 ounce per cubic inch [oz/inch³] .
Jul 30, 2012· After that, weight the aggregate mass that is inside the container and divide it by the volume of container. This will give you the bulk density of the loose aggregates. Compacted Bulk Density. Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod.
Compaction of earth fill is a very important stage of construction projects. Degree of compaction is defined by relative compaction. The relative compaction of a compacted earth fill is calculated by dividing the dry unit weight obtained from in situ tests by-into the maximum dry unit weight obtained from laboratory compaction tests.
Jul 24, 2009· Strictly speaking, unit weight has units of force/(length^3). Therefore, lb/ft^3 or, kN/m^3. Unit mass would be kg/m^3 or slugs/ft^3. Calculation of static forces and stresses is often easier with unit weight, since you don't need to multiply by 32.2 or 9.81.

5.1 This test method can be used to determine the in-place density and unit weight of natural inorganic soil deposits, soil-aggregate mixtures, or other similar firm materials. It is often used as a basis of acceptance for earthen material compacted to a specified density or percentage of a maximum density determined by a test method, such as Test Methods D698, D1557 or D4253.
During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume. If we know the bulk density of the aggregate material then we can easily determine the mass required to fill a unit volume container.
1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.
