Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.

Aggregates shall be obtained from a source listed in the MTO's pre-qualified products list for coarse aggregates for HL 1 or Superpave 12.5 FC1 hot mix. Aggregates containing slag are not permitted for use in a chip seal application.

The asphalt binder, which is the glue that binds the aggregate, provides waterproofing, flexibility and durability. Aggregate is primarily responsible for the load-supporting capacity of a pavement. Aggregate types are natural or uncrushed (smooth and round)—or crushed with single or multiple crushed faces.

A pit is an open excavation of aggregate from an existing natural source i.e. sand pit, gravel pit. A quarry is an open excavation from which aggregate is obtained through blasting the rock with explosives. A mega-quarry is defined as having 150 million tonnes of reserves and an annual production capacity of at least 10 million tonnes.
