How does soil compaction relate to aggregate base performance?

Soil compaction plays a critical role in the performance of aggregate bases, primarily by increasing the load-bearing capacity of the material. When soil is compacted effectively, the arrangement of particles is optimized, leading to a denser configuration. This denser arrangement minimizes the air voids between aggregate particles, which results in a more stable and firm base.

By improving the density of the aggregate, compaction enhances the ability of the base to bear loads without experiencing significant deformation or failure. This behavior is crucial in a variety of applications, such as road construction, where heavy traffic loads are expected. A well-compacted aggregate base can distribute loads more evenly across the surface and helps to prevent issues like ruts and cracks.

This relationship highlights the importance of adequate compaction techniques and equipment used during construction to ensure that the aggregate base maintains its integrity and performance over time, especially under load.
