please solve problem 2 Problem 1:A standard Proctor test was conducted on a silty clay soil collected from a proposed construction site. Theresults are shown in the following table. (Gs = 2.7)Mass of moist soilin the mold (g)MoistureTrial no.content (%)1168912.7175215.03180017.84184520.6184423.8Using the compaction test data determine the optimum moisture content and the maximum dry unitweight.Plot the zero-air-void curve and check whether it intersects the compaction curve.Plot the void ratio and the degree of saturation against the moisture content.What are the void ratio and degree of saturation at the optimum moisture content?If the specification calls for 95% DOC, What the is least acceptable field dry density?Problem 2:Refer to the silty clay soil at the construction site in Problem 1. As part of a quality control program, the fieldinspection engineer conducted a sand cone test to determine the field density. The following data were recordedusing the sand cone method.Calibrated density of the used sand is 1667 kg/m³Mass of sand needed to fill the cone (only the cone) is 0.117 kgMass of jar + cone + sand before use is 6.1 kgMass of jar + cone + sand after use is 2.83 kgMass of moist soil from the hole is 3.35 kgMoisture content of moist soil 16.1%Determine:A. The dry unit weight of compaction in the field?B. The relative compaction (DOC) in the field?C. Was the compaction specification stated in Problem 1 met?D. Field void ratio and degree of saturation?

Note : - Hi, thank you for the question. As per our Honor code, we are allowed to attempt first…
