(natural and used coarse aggregates) are given in table 3.1. From the table, it can be seen that the aggregate impact value for discarded or used aggregate (24.17%) is higher than that of the natural aggregate (20.73%) which implies that the discarded aggregate is lower in strength than the natural aggregate.

Specifications for construction aggregates have been developed for a variety of construction applications. The most important construction materials specifications for aggregates are for roadway and pavement construction (including hot-mix asphalt, granular base and granular sub-base), and for concrete materials used in buildings, civil engineering structures and infrastructure construction.

Also, the eighth five-year-plan envisaged that there was a shortage of coarse aggregates in the housing sector. Further, to achieve the target for road development up to 2010, an estimated 750 million cubic meters of coarse aggregate as sub base material will be required. The use of Recycled Coarse Aggregate (RCA) can fill this gap in part.

The smallest of all gravel sizes is usually size #10, which is also commonly known as screenings gravel. This gravel is typically around 1/8th of an inch (0.32 centimeters) in diameter, making it similar in appearance to coarse sand. Often, screenings gravel is used as the base for bricks, paving stones, and other similar items. In some cases
