Most category Gc aggregates can be used as a trench fill drainage stone, as the void space between aggregate particles allow water to flow through. If the rock quarried is resistant to the polishing action of vehicle tyres, aggregate of size 14/20 Gc 85/20, when coated with 1.5% bitumen, is called pre-coated chippings or pre-coats.

A Detailed Guide on Grading of Aggregates.

Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up.
