A sample of field soil is tested in the laboratory. The results of Standard and Modified Proctor tests at optimum moisture content are given in the Table below: Standard Proctor test Modified Proctor test Mass of wet soil in the mold (g) Volume of Proctor mold (cm) Optimum moisture content (%) 1800 2000 900 1000 12 10 At the field, a sample of 600 cm3 of this soil weighted 1200g. The weight of water in this sample was 200 g. Find the following: 1- Degree of compaction (Relative compaction) (R%) at Standard Proctor test. 2- Degree of compaction (Relative compaction) (R%) at Modified Proctor test.
