Sustainable concrete pavements for low volume roads-Scientometric analysis of the literature

Abstract

Developing countries like India invest huge amounts of money for the construction and maintenance of different roads which includes all types of roads. In this research paper a critical review of literature on sustainable pavements for low volume roads was made using sustainable materials for paving Ultra-thin white topping concrete overlays sustainable new pavements like Pervious concrete pavements, Roller compacted concrete pavements, Cell filled concrete pavements, Self-Compacting Concrete (SCC) Pavement and additional discussion on energy harvesting pavements done. Ultra-thin white topping concrete overlay has better-proven performance but interface bond strength is very critical to resist shear stresses which cause debonding of composite concrete layers. The porous cement or bituminous concrete helps to recharge the groundwater reducing the heat islands and makes nature eco-friendly but on the other hand clogging effect can retain the water in the pavement and causes failure of the pavement. Roller compacted concrete pavement, Self-Compacting Concrete (SCC) Pavement and cell-filled concrete pavements are good in terms of performance disadvantages are less. The Indian standard code should be developed to implement energy harvesting pavements that help to produce electrical energy which meets the need of society. Further Scientometric analysis of sustainable concrete pavements for low volume roads done using VOS viewer software and the database of research work from Dimensions software. From the research gap in keyword occurrences on this topic, it is observed that rice husk ash, recycled aggregate, aluminum dross and fatigue, modulus of elasticity has a wide gap indicating further research on the combination of these key words make sustainable concrete pavements further discussed regarding high impact research papers published, similarly countries were discussed in detail.
