Which of the following is NOT an objective of proper compacting?

Proper compaction of soil is essential in civil engineering to ensure stability and longevity of structures. The objectives of compacting soil generally include minimizing settling, increasing soil stability, and enhancing the load-bearing capacity of the soil.

Minimizing settling is crucial because well-compacted soil will reduce the likelihood of future settlement under loads. Increases in soil stability are vital as compaction interlocks soil particles, making the mass more cohesive and resistant to lateral and surface failures. Also, enhancing the load-bearing characteristics is an objective because compacted soil can support greater loads without structural failure, which is essential for the construction of roads, buildings, and other structures.

On the other hand, enhancing water penetration is not an objective of proper compacting. In fact, compaction typically reduces the void spaces in the soil, thereby decreasing the permeability and water movement through it. Excessive compaction can lead to poor drainage conditions, which can worsen issues like erosion or flooding. Therefore, the statement regarding enhancing water penetration accurately identifies an objective that is not aligned with the primary benefits of soil compaction.
