Jan 13, 2009 Unit weight (old term 'bulk density') is the weight per volume of the granular material I think in your case, dry density and dry unit weigh mean the same thing Unit weight is the preferred term, because dry density can be confused with density Lead Through Practical Exercise Field Density(Sand .
I can see the searches people put in to reach my site, and a recurring one is "density of type 1 subbase" So in my humble option you should use 21 / 22 t/M3 for aggregate that has a relative density of 27 / 28 t ,
SECTION 301 MATERIALS FOR SUB-BASE AND BASE COURSES 30101 SCOPE A This section covers the requirements for the characteristics, source, supply and storage of sub base and base course pavement materials B Materials specified for use in the construction of sub-base and base courses for flexible and rigid pavements include the following:
In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicl Subbase is ,

10/11/2012 4 Road Aggregate 101: Property of Plasticity • The plasticity index (PI) is a measure of the plasticity of a soil Soils with a high PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 (non-plastic) tend to have little or no silt or
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
2010 Standard Specifications allowed up to 100 percent use of recycled aggregate for both base and subbase 2006 Standard Specifications originally only allowed up to 50 percent use of recycled aggregate for subbase or base, but were amended in 2007, see below These specifications can only be used for projects until Dec 1, 2012
unit weight of subbase unit weight of subbase TB011P - dotstatemnus subbase layer may be needed In this publication, a subbase is defined as the layer of ,
subgrade or subbase to create a layer with structural value in the pavement system The treated soils may be in-place (subgrade) or borrow materials Subgrade stabilization usually involves in-place “road mixing,” and generally requires adding 3 to 6 percent lime by weight of the dry soil2
Volume to weight, weight to volume and cost conversions for Refrigerant R-22, liquid (R22) with temperature in the range of -5112°C (-60016°F) to 7112°C (160016°F) Weights and Measurements long ton per square yard (long tn/yd²) is a non-metric measurement unit of surface or areal density
Quantities of [subbase] [and] [select-material subbase] [or] [rigid pavement base] course, determined as specified above, will be paid for at the respective contract unit prices, which will constitute full compensation for the construction and completion of the [subbase] [and] [select-material subbase] [or] [rigid pavement base] course
Application Rates and Weights for Estimating Purposes Material : Application Rate or Unit Weight ; Aggregate Base 2225 kg/m 3 (1390 lb/ft 3) Hot Asphalt Mix 2325 kg/m 3 (1452 lb/ft 3) Asphalt Binder 60% by weight of mix : , Application Rates and Weights for Estimating Purposes
As specific gravity is just a comparison, it can be applied across any units The density of pure water is also 624 lbs/cuft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 073 then we can calculate that its density is 073 x 624 = 45552 lbs/cuft Note, kg/cum divided by 1602 = lbs/cuft
Jul 30, 2012· Definition:Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume , 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 aggregat
The objective of this study is to establish a satisfactory method of determining maximum density of cohesionless material, such as subbase, that will provide compaction criteria for these materials and be compatible with current methods of density determinations in the field
2 Clay borrow sub-base material will be of a type approved by the Contract Administrator 3 Crushed sub-base material will be crushed aggregate, crushed granite, crushed limestone or crushed concrete pavement 4 Crushed sub-base material will be well-graded and conform to ,
Note: The use of a sub-base layer is still acceptable FDM 14-5 Subgrade and Base Course Page 2 52 Policy 521 Concrete Pavements , When produced from a quarry, it is expected to have a lower unit cost than 1 1/4-inch base, since less crushing effort will be required

Unit Weight – the unit weight of the aggregate used in stabilized base and subbase mixtures is an indicator of the compacted density of the mix containing this aggregate Deleterious Substances – aggregates used in stabilized base and subbase mixtures should be reasonably free of deleterious substances, such as clay, shale, coal, coke .
Jun 09, 2005· A common practice of industry professionals is to divide TONS by (2) to get CY Dividing TONS by (2) to get CY assumes that the in place aggregate will have a density of 148 lb/ft^3 However, a differential of a couple of units (148 vs 165) makes a big difference in cost on big projects
Units This Report predominantly uses US Customary Units because they are common to both the construction methods and referenc However, SI units are used to facilitate precise measurements of rut depth Some useful conversions are shown below: 1 inch = 25 mm 1 pcf = 1602 kg/m³ 1 foot = 0305 m 1 tsf = 139 psi = 958 kPa
* The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre” * The bulk density reflects the volume taken up by the cement plus any air trapped between the p.
