aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density

Schools and hospitals require 15,000 tons of crushed stone. 1 mile of fourlane interstate requires 85,000 tons. 99% of the crushed stone mined in an area stays in that community.
Finally to calculate the weight of gravel required, multiply the volume with the density of the material. Let's assume that the density of the material is kg/ft3. Weight of gravel required should be x 100 = kg
Dense graded crushed stone is available in a number of sizes. Being a crushed stone product and well graded, these products spread and compact quickly. Rail Road Ballast Stone
