Applications of reclaimed asphalt pavement in India – A review

Stepping in the 21st century, the materials used in pavement construction have diversified and progressed with time. Due to an increase in the cost of materials, depletion of natural resources, and accentuation on environmental sustainability, the usage of recycled asphalt pavement material has become popular worldwide. However, there appears to be inadequate works and a gap in understanding the method of recycling and its concomitant economic and environmental benefits at a commercial level in India. The majority of studies have focused on base and sub-base courses, whereas few works have been conducted for the surface course. Furthermore, India is a growing powerhouse in South Asia, and the pavement industry constitutes a vital sector. Thus, the reuse and recycling of reclaimed asphalt pavement in India is an emerging domain, but their usage is in low amount as compared to the United States, Europe and Japan. Hence, the objective of this review paper is to provide information on the suitability and utilization of reclaimed asphalt pavement in various areas of pavements that will eventually contribute to creating a balanced system in solving the environmental and material scarcity, economic benefit and consequently transform the construction industry to sustainable and eco-convivial.
