The purpose of this paper is to study the important engineering properties of the volcanic rocks present with the Nagar Parkar Granites located from
Sindh University Campus Jamshoro 5 h 44 min (355.3 km) via Hyderabad - Badin Road and 5 h 57 min (323.5 km) via Naukot - Mithi Road and
Islamkot, the rocks look suitable for pavement and concrete aggregates. Number of standard tests were conductedted. Which included; Specific Gravity,
Gradation, Soundness, Particle shape and Surface Texture Absorption Index, Abrasion Resistance, Deleterious Materials, in addition to moisture content
and Fineness modulus. Geologically there are two main components known as Pink Granites and Grey granites on the basis of the plagioclase / orthoclase
mineral component [1]. Results of the standard tests depicted that both Pink Granites and Grey Granites samples have different characteristics especially
concerning abrasion resistance. After comparing the obtained results with standard specifications showed that both samples can produce aggregates
that are suitable for pavement but only Pink sample can produce concrete aggregates. It was also assumed that there should be a technical control in the
crushing circuit to produce the required gradation.
