A Proctor compaction test is performed on a soil PRIMARILY to determine its:
a.Chemical composition
b.Maximum dry density and optimum moisture content
c.Color and texture classification
d.Load-bearing pressure in psi
Explanation
The Proctor test establishes a soil's maximum dry density and the optimum moisture content at which that density is achieved, which is then used as a compaction target in the field. It does not measure chemical composition, classify color, or directly report an allowable bearing pressure.
