COST EVALUATION OF PRODUCING DIFFERENT AGGREGATE

Aggregates are defined as inert, granular, and inorganic materials that normally consist of stone or stone-like solids. They can be used alone (in road bases and various types of fill) or can be used with cementing materials (such as asphalt cement or Portland cement) to form composite materials or concrete (Guimaraes et al., 2007).
