Asoil sample was taken from the site of a proposed borrow pit and sent to the laboratory for a standard proctor test (astm d 698). results of the test are as follows: determination number 1 2 3 4 5 dry unit weight (lb/ft3) 107.0 109.8 112.0 111.6 107.3 moisture content (%) 9.1 11.8 14.0 16.5 18.9 plot a moisture content versus dry unit weight curve and determine the soil's maximum dry unit weight and optimum moisture content.
