Application of Foam Bitumen in Asphalt Pavement Recycling: A Case Study

The asphalt paving industry is constantly exploring technological improvements that will enhance the material’s performance, increase construction efficiency, conserve resources, and advance environmental stewardship. There is a need for immediate attention towards the implementation of sustainable and environment friendly pavement construction technologies. Recent advances in asphalt technology around the world have made cold recycling an increasingly popular and cost effective pavement construction and maintenance technique. India has also started adopting sustainable road construction technologies like warm mix asphalt, cold mix asphalt and recycling of asphalt pavements. This paper presents the feasibility of producing high quality cold recycled asphalt using foam bitumen for a heavily trafficked national highway of India. Foam bitumen stabilization was used to rehabilitate the existing base layers of pavements incorporating thick asphalt layers, resulting in higher percentages of Reclaimed Asphalt Pavement (RAP) in the mix. Energy conservation and reduction in greenhouse gases (GHG) emissions were also monitored during the construction phase.
