Proctor test :
- A definite relationship is established between the degree of dry density and soil moisture content.
- The competitive effort is a moisture content of mechanical energy applied to the soil mass.
- OMC is the moisture content at which a particular soil attains maximum dry density (MDD).
- The maximum dry unit weight obtained is a function of compactive effort and methods of compaction for a particular type of soil.
- If the compaction energy is decreased then, γd will decrease with an increase in OMC.
- On increasing compactive effort, the curve shifts backward and upwards and OMC decreases, and MDD increases as shown by the graph below:
