Recycled Aggregates—Profitable Resource Conservation Aggregates are Required for Construction Projects Aggregates are composed of rock fragments that may be used in their natural state or after mechanical processing such as crushing, washing, and sizing. Natural aggregates consist of both sand and gravel, and crushed stone.
Soil Stabilization Where soil stability is at issue, the load-bearing capacity of that sub-grade can be improved through the incorporation of recycled aggregate, lime or fly ash. The process changes the water susceptibility of subgrade, thereby increasing stability.
