A fill material has 10% oversized particles. The compaction tests on the fill without oversized particles result in a maximum dry unit weight of 18.7 kN/m3 and its corresponding optimum moisture content of 12%. The oversized particles have specific gravity of 2.67 and saturated surface dry (SSD) moisture content of 3%. Calculate the corrected maximum dry unit weight and optimum moisture content including the oversized particles
