US4221603A - Mix design method for asphalt paving

A mix design method for determining the gradation of coarse and fine aggregates to be combined to achieve a predetermined percentage of air void volume and voids in mineral aggregates for a given quantity of asphalt cement. The method uses a volumetric value known as the Riguez Index which is derived from a compacted representative sample of fine aggregates to be used in the mixing plant.
