The undisturbed soil at a given borrow pit is found to have the following properties: w = 15%; y = 19.1 kN/m³; G, = 2.70. The soil from this borrow is to be used to construct a rolled fill having a finished volume of 38,500 m. The soil is excavated by means of a shovel and dumped onto trucks having a capacity of 4.80 m³ each. When loaded to capacity, these trucks are found to contain, on average, a net weight of soil and water equal to 72.7 kN. In the construction process, the trucks dump their load on the fill, the material is spread and broken up, after which a sprinkler adds water until the moisture content is equal to 18%. The soil and water are thoroughly mixed by a disc (or similar equipment) and then compacted until the dry unit weight is equal to 17.3 kN/m?.
