After compaction the field unit weight of the soil is determined by means of the sand cone
method, the following are the results:
Calibrated dry density of Ottawa sand = 1570 kg/m3
Mass of Ottawa sand to fill the cone = 0.545 kg
Mass of jar + cone + sand (before use) = 7.59 kg
Mass of jar + cone + sand (after use)
Mass of moist soil from the hole = 3.2 kg
%3D
%3D
= 4.78 kg
Moisture content of moist soil = 9.8%
%3D
Determine the maximum dry unit weight (kN/m³) of compaction and the optimum
moisture content. Given mold volume = 900 cm3. Note: Check the maximum dry unit
weight of compaction and the optimum moisture content using the graphical method
and by means of the equation of the line.
Determine the relative compaction in the field.
