Performance Evaluation of Sustainable Materials in Roller Compacted Concrete Pavements: a State of Art Review

In the recent past, emphasis was given roller-compacted concrete in the field of pavement construction owing to its proven advantages like fast construction method, high density, and economical when compared with conventional concrete. Roller compacted cement concrete is the name given to stiff concrete that can be compacted by a roller which is generally used in surface and base courses of pavements. Many marginal materials were used for developing sustainable roller-compacted concrete. In this paper, an effort has been made to consolidate the research done to date to make roller-compacted concrete a sustainable material for pavement construction. The feasibility of using various materials like reclaimed asphalt pavement wastes, recycled concrete aggregate, electric arc furnace slag, cross-linked polyethylene waste, silica fume, bagasse ash, ground granulated blast furnace slag, jarosite, crumb rubber, rice husk ash, fly ash, sugarcane ash, coal waste ash and coal waste powder explored by various researchers in the past were consolidated under one roof in this study. The effect of all the materials on different mechanical, durability and fresh properties of Roller-compacted concrete was reported in the study. Many of these materials yielded satisfactory results when partially replaced or partially added to various constituents of roller-compacted concrete. In essence use of these materials not only have environmental benefits like reduction of carbon footprints but also saves the cost of construction.
