Life-Cycle Cost Analysis of Brick Kiln Dust Stabilized Perpetual Pavements for Lowering Greenhouse Gas Emissions in India

To cater to the rising traffic in urban areas, engineers need to adopt design methodologies that ensure the resilience and sustainability of pavements for a longer duration than conventional life and demand construction of perpetual pavements. The rapid growing urbanization has led to a growth in the requirement of bricks, leading to massive accumulation of its by-products. Brick kiln dust is the mixture of coal ash, wood ash, and brickbats produced by fuel combustion in the brick kilns. Brick kiln dust finds its potential application in the design of perpetual pavements over weak subgrades. A comparison was drawn between perpetual pavements and conventional flexible pavements on economic and sustainability grounds, to serve for 50 years. The pavements were designed by mechanistic-empirical design philosophy using the design software IITPAVE. The results were further validated using the design software KENPAVE. This study aims to estimate the greenhouse gas (GHG) emissions associated with the life-cycle of perpetual and conventional pavements. Results show that the brick kiln dust treated perpetual pavements have significantly lower life-cycle costs and GHG emissions than the non-treated perpetual pavements. The perpetual pavements prove to be an economical and a sustainable choice for over the conventional pavements.
