density of a quantity of coarse aggregate particles (not includ-ing the volume of voids between the particles), the relative density (specific gravity), and the absorption of the coarse aggregate. Depending on the procedure used, the density (kg/m 3(lb/ft )) is expressed as oven-dry (OD), saturated-

Bulk density is a fundamental property of coarse aggregate that is used to determine the weight per unit volume of a given material. It is an important parameter for various construction activities and engineering applications. Bulk density of coarse aggregate refers to the density of the aggregate with all the voids present in it.

Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.

The unit weight of a material can be defined as the weight of a given volume of graded aggregate. It effectively measures the volume that the graded aggregate will occupy and includes both solid particles and the voids between them. The unit weight of fine and coarse aggregates within the ASTM grading limits are generally in the range of 1450 – …
