The parametric comparison of perpetual pavements with respect to Life-cycle cost and greenhouse gas emissions

Abstract

The Present Study does parametric comparison of perpetual pavements designed as per IRC 37 (2018) guidelines. The comparison is executed among various combination of flexible pavement mentioned in IRC guidelines designed with perpetual pavement concept. The comparison is carried out on the grounds of checking the effect of change in thickness of sub base and base layers of pavement compositions with respect to overall thickness, life cycle cost assessment and carbon dioxide emissions. IITPAVE software was used to design perpetual pavements. The results were then verified using the KENPAVE software.The study concludes that change in thickness of sub base and base layers in case of various combinations of perpetual pavement results in considerable change in overall pavement thickness, total lifetime cost and CO2 emission. Results also show that deep strength perpetual pavement is proven to be most economical and eco-friendly option.
