Soil Compaction Experiment

Compaction is a method of mechanically increasing the density of soil, and it’s especially valuable in construction applications. If this process is not performed properly, soil settlement can occur, resulting in unnecessary maintenance costs or failure of the pavement or structure.

Lab Report #3: Standard Proctor Test for Soils Abstract Soil Compaction is the process in which stress is applied to a soil which causes densification as the voids are filled with solids. This plays a vital part in construction for soils are mainly used as supports for a lot of infrastructures ...

6 Laboratory Procedure Generally before any soil compaction occurs, various samples of the proposed embankment or fill are analyzed in the Lab. One such lab test is Proctor compaction test.
