What is one of the primary purposes of using an aggregate base for concrete pavers?

One of the primary purposes of using an aggregate base for concrete pavers is to provide structural support. An aggregate base consists of a mixture of crushed stone, gravel, and sand, which creates a stable and durable foundation for the pavers. This base helps distribute the load from the pavers evenly across the surface, preventing shifting or settling over time, which is essential for maintaining the integrity and longevity of the paved area. By ensuring that the pavers have a solid and well-drained foundation, the risk of cracks or instability associated with heavy loads or environmental stresses is significantly reduced. This structural support is crucial in applications such as driveways, patios, and walkways where the physical performance and durability of the paving system are important.
