What is the recommended practice for compacting soil?

Testing moisture content before compacting is essential because the effectiveness of soil compaction largely depends on its moisture content. Each type of soil has an optimal moisture content range that, when reached, allows the soil particles to arrange themselves more densely, providing greater stability and structural integrity. If the moisture content is too low, the soil particles may not stick together effectively. Conversely, if it is too high, the soil may become too plastic and lose strength during the compaction process. Therefore, checking and adjusting the moisture content ensures that the soil can be compacted to its maximum density, leading to a more stable and durable surface in construction projects.
