Due to high strength, durability, economy and better serviceability there is a growing interest in the construction of concrete structures such as pavements. The main concentration nowadays is towards the production of thinner and green pavements of good quality which can sustain much heavier loads. High strength steel fibre concrete is a concrete that possesses strength greater than 40 MPa and is made of hydraulic cement, fine and coarse aggregates and unconnected, discontinuous, randomly distributed steel fibres. The aim of this study was to develop pavement quality control mixture including marble dust as a partial replacement of cement as well as admixtures. In this study, the flexural, compressive and split tensile strength for pavement quality concrete mixture for different percentage of steel fibre and replacement of cement with marble dust were reported. For 1% steel fibre and 0% marble dust, increase in compressive strength, flexural strength and split tensile strength is maximum. Also it has been made possible to achieve savings in cement by its replacement with marble dust and additional fibres. This study also reveals that in view of higher values of split tensile strength, flexural strength, compressive strength, higher life expectancy and higher load carrying capacity, the combination of 20% marble dust with addition of 0.5%-1% steel fibre is ideal for a rigid pavement that has the above mentioned characteristics.
