What is the purpose of a soil compaction test?

A soil compaction test is crucial in evaluating the structural integrity and suitability of soil for construction projects. The primary purpose of conducting this test is to determine the maximum dry density of the soil when compacted and assess its suitability for supporting structures. By knowing the maximum dry density, engineers can optimize the compaction process to ensure that the soil achieves adequate strength and stability, which are essential for the longevity and safety of the construction.

This process helps identify the most effective moisture content for achieving the desired compaction, ultimately affecting the load-bearing capacity of the soil. The results of the soil compaction test guide construction practices and materials selection, ensuring that the foundation for roads, buildings, and other infrastructure is solid and reliable.
