Aggregates may also be used as special backfill material, ripr ap, mineral filler, and other less significant uses. COMPACTED AGGREGATES Compacted aggregates without the addition of a cementing material may be used as a base or subbase for hot mix asphalt and portland cement concrete pavements. Portland cement concrete pavements are rigid pavements.
