The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. The aggregates are broadly classified into two types based on the size, namely fine aggregate and coarse aggregate. In this article, we discuss [ ].Aggregate is used as a base course supporting other paving materials. Typically, a ﬂ exible pavement calls for two subcourses of different aggregates. A graded course of gravel or crushed stone, provided for stability and drainage, may be topped with a ﬁ ner course like sand to serve as a leveling or setting bed for unit pavers.
