This paper investigates the interrelationships between the engineering properties of igneous aggregate rocks from Greece with the aid of the Rmode factor analysis. The collected samples represent mafic and ultramafic rocks from the ophiolite complexes of Gerania, Guevgueli, VeriaNaousa, and Edessa as well as intermediateacidic rocks from the surrounding areas of the complexes.

Recycled Concrete Aggregates (RCA) as sustainable aggregates in Hot Mix Asphalt (HMA) is therefore investigated in this research project. The objective of this study is to characterize the mechanical properties of asphalt mixtures with recycled concrete aggregates for low volume roads (herein, the equivalent standard axle load number is low).

Classification and Properties of Aggregates as per IS 456:2000 Aggregates constitute nearly 70 to 75% of the total volume of concrete and are essentially inert in nature. Aggregates have two prime functions, namely, to provide concrete with a rigid skeletal structure and reduce the void space to be filled by the cement paste.
