The quantity of bitumen by weight of the mix is measured and poured into the heated aggregate. The mix is uniformly blended and poured into a standard cylindrical mould (102 mm diameter and 64 mm depth) heated to 93-149°C. It is compacted with 75 blows of a rammer of weight 4.54kg with a fall of 45.7 cm on each face.
Crushed gravel comes in the same form that it's found, there are no additives or other stones mixed in. And due to its organic nature, unlike crushed stone, you won't find gravel having many ragged edges. It comes in a more smooth and rounded package. But crushed gravel has all the same uses and can be interchanged with crushed stone.
