35 行Approximate Weights of Various Construction Material Per Cubic Yard. Most of Harmony …Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the

weight of rollers to compact the material to the required density. Compact the aggregate base course in-place to a field target density of at least 100 percent and a lower specification limit (L) of at least 97.0 percent of the maximum density of laboratory specimens prepared from samples of base course material delivered to the job site.aggregate, and subtract the tare mass of the empty measure to obtain the net weight of the aggregate required to fill the measure. (5) Repeat the above steps until a total of three weight determinations are obtained, which do not differ by more than 1 %. F. CALCULATIONS. 1.Calculate the average net weight of aggregate required to fill the measure.

Construction Aggregate Calculator. Enter the width, length, thickness, and product density and hit the "Calculate" button to calculate your estimate. If you do not know the product density, use the optional density estimator* or contact a local sales representative.Also, what is aggregate unit weight? The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a container of a specified unit volume. Bulk Density = Mass / volume.Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3.. One may also ask, what is the density of aggregate base? The (150-180) density data comes ...

a. Class 1 aggregate base shall consist of crushed stone or gravel, free from vegetable matter and other deleterious substances. Aggregate shall consist of material of which 90 percent by weight shall be crushed particles. Composition of aggregate base, in percentages by weight, shall conform to one of the following gradings,If aggregate base is paid for by weight, refer to the discussion of weighing and metering procedures in Section 3-902E, "Weighing Equipment and Procedures," of this manual. If aggregate base will be paid for by volume, calculate the volume based on the dimensions shown on the plans.

F:Truck Body Pricing & BrochuresExcelCubic_Yardage_Chart DCubic_Yardage_Chart D Rev A 6/9/2015 AGGREGATE TYPESeveral sources state that "most natural" aggregates have particle densities between 150 and 181 (lb/ft^3). In the Civil Engineering Reference Manual (CERM), under chapter 48, "Properties of Concrete and Reinforcing Steel" Pg. 48-2, "Aggregate" states that, "Most sand and rock aggregate has a specific weight of approximately 165 (lb/ft^3).
