aggregate is used? It is a good practice to test the aggregate before placing it on the road.Also, if the tests fail, you can work with the crushing contractor to try to blend and improve or reject the material. This becomes even more critical in producing material for pavement or base
Base/SubBase Filler. Crusher run is the most commonly selected base filler material and is the best suited product for this purpose. Why: Despite the fact that there are many ways in which crusher run can be used, one of its main functions is as a base or subbase filler.
It is produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Densegraded base course refers to aggregates with a range of particle sizes, usually 11/2inch and smaller, that produce a dense layer of stone with a minimum amount of voids. Primarily uses include pavement and construction appliions.

Using crushed concrete as aggregate conserves resources
The most common appliion is for base course. The cost of using recycled aggregates for base material includes only the cost of crushing operations. Breaking, removal, steel separation, and transportation costs are incidental. When using recycled aggregate in concrete, no special handling, batching, or mixing procedures are necessary.
