Q1-A construction site requires 100m3 of soil compacted at the maximum dry density estimated from laboratory standard compaction tests. Laboratory tests indicate the optimum moisture content is 12% and the degree of saturation at optimum is 85%. If the specific gravity is 2.7. a) Calculate the weight of dry soil required at the construction site. b) Calculate the total weight of soil that needs to be transported to the site if it is extracted from a borrow pit with a moisture content of 5%.
