The technologic and socioeconomic factors involved in turning mineral aggregate resource into mineral aggregate reserves are discussed. The technologic approaches covered here include changing specifications, upgrading aggregates, using synthetic aggregates, changing cementitious materials and protecting exterior aggregate and concrete. A discussion of the socioeconomic factors considers the quantity and distance hauled, landscaping and rehabilitation, regional controls, upgrading operations, federal mining compensation, economic impact assessment, and guidelines for rules safeguarding the public interest. It is noted that the expansion of aggregate reserves is influenced to a far greater extent by the attitudes of the general public than by technology. Some success has resulted from showing how operations will be landscaped and the worked-out areas rehabilitated. Regional mineral resource zoning has only limited value. The mineral-resource base may be expanded by encouraging underground operations through zoning and by allowing special mining permits where the economic impact is not negative. Mineral resources can be expanded by substituting firm rules or guidelines for public hearings. It is suggested that the federal government institute 2 compensation systems: to compensate communities; and to compensate producers who mine underground.
