D1556 Standard Test Method for Density and Unit Weight of Soil in Place by the Sand-Cone Method B. State of California, Department of Transportation Standard Specifications (Caltrans):
The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume of gas-free distilled water at a stated temperature (Figure 2). This unit volume of aggregates is composed of the solid particle, permeable voids, and impermeable voids. Gsb = A / (B-C) Where: A = Oven dry weight.
The Specifications also require that any aggregate base course (ABC) ... The unit weight should be obtained from the most recent AASHTO T180 test results, which are obtained from the Soils Lab within the Materials and Tests Unit or from the following website:https: ...

Aggregate Base Course . Aggregate Base Course often referred simply as ABC, has certain desirable properties. Base Course in pavements refers to the sub-layer material of an asphalt roadway and is placed directly on top of the undisturbed soil (Sub-Grade) so as to provide a foundation to support the top layers of the pavement.

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.

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 ...
