characteristics and strength of the aggregate (Okeke, 2005). Crushed rock aggregates are essential as an aggregate for road pavements. They also form part of the component of concrete. The strength of any rock aggregate is its ability to resist and withstand compression from external load, either dynamic or static (Prentice, 1984).
