Classification Of Aggregate Aggregate classification. The classification of Aggregate is generally based on their geological origin, size, shape, unit, weight, etc. Aggregate is the major ingredient of concrete. Aggregate is derived from rocks. They are broadly divided into two categories i.e. fine and coarse aggregates.

Jun 09, 2005· Several 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).

20 mm 10 mm 4.8 mm Fine Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension i.e. the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now if the least dimension is less than18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky.

The maximum unit weight is sometimes called the "solid density". This value is based on the asphalt mixture's maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF). For example, 2.500 is a typical Rice value. 2 ...

The loose unit weight is used to calculate the air voids expected between the chips after initial rolling takes. It depends on the gradation, shape, and specific gravity of the aggregate.

Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties and dimensional stability.

Basic HMA weight-volume relationships are important to understand for both mix design and construction purposes. Fundamentally, mix design is meant to determine the volume of asphalt binder and aggregates necessary to produce a mixture with the desired properties (Roberts et al., 1996 [1]).). However, since weight measurements are typically much easier, they are typically taken then …
