What factor can affect the success of soil compaction?

The moisture content of the soil plays a critical role in the success of soil compaction because it directly influences the soil's cohesiveness and its ability to achieve maximum density. When soil is too dry, particles do not stick together well, resulting in insufficient compaction and potentially leading to settling or erosion later. Conversely, if the soil is overly saturated, it can become too pliable, preventing effective compaction as well. There exists an optimal moisture range, usually observed as the moisture content at which the soil achieves its maximum dry density, also known as the optimum moisture content. This balance is essential for achieving strong, stable foundations necessary for construction and preventing future structural issues.

Understanding how to manage moisture content effectively allows for better preparation during the compaction process, ensuring a solid, lasting outcome for various construction projects.
