The resistance to polishing of aggregates can, however, be expressed as the polished stone value which is determined in the laboratory using an apparatus for accelerated polishing. The correlation between the polished-stone value and the skid resistance, i.e. the similarity with practice, appears to be good in cases in which the surface consists of a continuous mosaic of coarse aggregate such

Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers.It is distinct from gravel which is produced by natural processes of weathering and Crushed And Uncrushed AggregatesCrushed and uncrushed aggregates
Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
