Standard Proctor Test; Its Apparatus, Procedure, Result.

1. (10 marks):Standard Proctor compaction tests were conducted on a sandy clay (35% sand, 55% clay, and 10%silt), taken from a borrow pit. The tests suggested a maximum dry unit weight of 20.7 kN/m³. Thesandy clay in the borrow pit has a porosity of 65%, a water content of 5.2%, and the specific gravityof solids of 2.7. A roadway is to be constructed using this soil, at 95% of the maximum dry unitweight and a water content of 8.4%.a) Determine the dry unit weight of the soil in the field (i.e. r
