assume you are using dry gravel with a swell percentage of 15 and a shrink percentage of -7. plug those values into the calculator and it will tell you that the compaction factor 1.237. multiply the 1185 cubic yards by 1.237. 1185 1.237 1465.9. to complete this job you will need 1465.9 cubic yards of this gravel in loose state volume.
answer (1 of 2) thanks for ask bro coarse aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. it should be hard, strong, dense, durable, and clean. it must be free from veins, adherent coatings and injurious amounts of
aashto 57 stone specs aashto 57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, 7 stone. this material cannot be compacted in a true sense, but can be properly oriented with compaction equipment. this is particularly important when using 57 stone under flexi-pave surfaces.
typical gravel density (dry) is between 1520 and 1680 kg/m3 (95 to 105 lbs/ft3). if it is mixed with sand the density is around 1920 kg/m3 or 120 lbs/ft3 1. crushed stone is often used as a material for producing concrete.
jan 23, 2020 the densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. this isnt as complex as you may think because waters density is 1 gram per cubic centimeter or 1 g/cm 3. therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
