Typically, the benefits of using crushed aggregates outweigh the advantages of rounded aggregates when considering bond and strength The needed amount of cement paste is dependent upon the amount of aggregate voiding that must be filled and the surface area that must be covered , The voids left by larger particles are filled by smaller .Air voids are a reverse proportion of the density of the compacted mix By specifying a density requirement, the voids are inversely controlled , Paving on a firm, stable, well-draining crushed aggregate base might be given more leeway than a thin asphalt overlay Raining or not, new pavement must be placed on a firm, unyielding base.
