Excavated soil weight
WebThe in-situ moisture content of a soil is 18% and its moist unit weight is 105 pcf. The specific gravity of the soil solids is 2.75. This soil is to be excavated and transported to a construction site, and then compacted to a minimum dry weight of 103.5 pcf at a moisture content of 20%. a) How many WebWhen excavated, the material breaks up into different size particles that do not fit together, creating voids that reduce the weight per volume. For example, to hold the same weight of one cubic meter/yard of material, it takes 30 percent more volume (1.3 times) after excavation if the swell is 30 percent. Load Factor: The ratio of the loose ...
