Dense graded mixtures rely on a tightly packed aggregate structure in which the coarsest particles form a skeleton and the smaller particles fill the voids between them. This filling action reduces void spaces, increases inter-particle contact, and creates a cohesive, interlocked mass that resists deformation under traffic. The gradation is designed so that fines and intermediate sizes bridge gaps between the larger aggregates, helping to achieve higher stability and lower permeability while maintaining adequate binder film. In short, filling the voids between coarse aggregates with smaller particles is exactly how these mixes gain stability, so the statement is true.
