Soil is excavated and transported from a borrow pit to a construction site. The total volume of the constructed earth structure is 10,000 m 3
. Construction specifications require the soil to be compacted at a moisture content of 19.6% achieving a dry unit weight of 17kN/m 3
. It was determined that at the borrow pit the specific gravity of solids (G 3
) is 2.70, the moisture content is 15%, and the dry unit weight is 15kN/m 3
. When loaded on trucks for transport, the soil loosens and its dry unit weight drops to 14kN/m 3
. Use the following notation: Stage A is excavation at the borrow pit, Stage B is transport on trucks, and Stage C is the construction. Please determine the following quantities: a) The volume of soil to be excavated at the borrow pit. b) The number of trips of trucks between the borrow pit and the construction site assuming that each truck can carry 10 m 3
of loose soil. c) The volume of water in cubic meters to be added at the construction site to achieve the desired moisture content before compaction. d) The degree of saturation of soil at the construction site after compaction. e) If saturated after construction (due to rainfall), what is the moisture content of the compacted soil?
