Dense graded mixtures are designed to optimize the distribution of aggregate sizes in order to fill the voids between larger coarse aggregate particles using smaller particles, such as fine aggregates and fillers. This concept is essential in paving, as it helps create a compact and strong mixture that improves the structural integrity and durability of the asphalt pavement.

By effectively packing the aggregates together, dense graded mixtures achieve lower air void content, which contributes to a higher density and less permeability. This reduces the potential for water infiltration, thus enhancing the longevity of the pavement and minimizing issues related to freeze-thaw cycles, fatigue, and moisture damage. The goal is to create a uniform mixture that allows for a smooth and resilient driving surface.

As a result, the statement accurately reflects the purpose of dense graded mixtures in asphalt paving.
