The State of Flat and Elongated Aggregate Requirements for SMA

The production of SMA aggregate is believed to cost approximately twice that of conventional aggregate production. In some cases, quarry managers have decided that it is not cost-effective to produce the aggregate that meets the cubical stone requirements. This has resulted in limited availability of SMA stone in some areas of the country.
