Roads are an important component of the world’s transportation infrastructure and economy, thus necessitating sustainable design and construction methodologies to ensure optimized pavement construction. About 15000 tons of natural aggregates are required to build every kilometer stretch of a highway in India. In the US, annually about 1300 million tons of natural aggregates are being used in the pavement construction. The pavement industry is not only consuming huge amounts of natural resources worldwide but is also responsible for the global energy consumption, air pollution, greenhouse gas production and fossil fuel burning across the world. If these adverse effects are not addressed consciously during the design and construction phases of pavements now, the coming generations will have to pay for the huge loss. One of the alternatives available is to recycle the existing distressed pavements and use the reclaimed materials in new pavement construction. Furthermore, the cost of virgin aggregates (VA) is alarming and necessitates the use of high percentages of recycled materials in pavement construction. The utilization of reclaimed asphalt pavement (RAP) material in road construction has been proven to reduce both the amount of construction debris disposed-off in the urban landfills and the rate of depletion of natural resources. It has also resulted in considerable savings in terms of money, energy and carbon credits with equal or better performance with nominal stabilization.
