Figure 2 shows a cross-section of a 7 km ditch that is going to be filled with compacted SSD coarse aggregates. If the unit weight of the compacted aggregates is 1750 kg/m3 and the SSD specific gravity is 2.45, calculate:

a. The SSD weight of aggregates needed (in tons).

b. The weight of the aggregates needed if the aggregate have 1.75% surface moisture and if the aggregates have 0.8% saturation potential.

c. Through the knowledge of specific gravity the aggregates and the unit weight, estimate the percentage voids in the compacted aggregates
