In a fill section of a construction site, 1600 m³ of moist compacted soils are required. The design water content of the fill is 14.5%, and the design unit weight of the compacted soil is 17.8 kN/m³. Necessary soil is brought from a borrow site, with the soil having 11.5% natural water content, 17.2 kN/m³ wet unit weight, and G, = 2.64. How much (in cubic meters) of the borrow material is required to fill the construction fill section? And how heavy is it?

An engineer ordered that the compacted base course for the construction of a new highway must have a void ratio of less than or equal to 0.80. You, the contractor, tested the compacted base course to have a mean value of moisture content of 14.6%, Gs = 2.81, and the moist unit weight of 18.2 kN/m^3. Does the compacted base course comply with the specification?
