A lso known as road base, the ¾" base course consists of crushed gravel that range in size from ¾" down to fine sand. Common uses include spreading and compacting under foundations and roads to provide a strong, stable base. It can also be used as backfill.
A wide range of materials can be used as unbound base and subbase courses including crushed quarried rock, crushed and screened, mechanically stabilized, modified or naturally occurring "as dug" or "pit run" gravels. Their suitability for use depends primarily on the design traffic level of the pavement and climate.

· To make ROC the quarry starts with the same limestone used for base course. ROC is crushed with the same equipment that produces base course. The difference is that ROC is what comes out to the crusher, with no tests performed on it. Without testing or guarantees, ROC is lower cost than base course, but the product is virtually identical.
G1 Crushed Stone for base course is not the same thing as crusherrun, and it is not just a matter of density that makes the difference. G1 Crushed Stone was developed from single stage crusherrun material when during the late 1950's some observant Engineers noticed that this material would sometimes, after a
