Pune is the second-largest city in terms of population in Maharashtra. It is also an industrial, cultural, and socioeconomic hub of Maharashtra. The traffic around Pune city has been increasing at high rate, thus necessitating increase of width of the existing roads. Besides, traffic originating outside Pune and destined outside Pune is passing through Pune City resulting in traffic congestion inside the city limits. Pune Ring Road is a proposed circumferential outer road for Pune metropolitan region to overcome this situation. The project road is proposed to be a six-lane rigid pavement having design life of 30 years as per provisions of Ministry of Road Transport and Highways (MoRT&H) Expressway Guidelines. This study aims to suggest an alternative of choosing perpetual pavement over proposed rigid pavement. There were no official standard provisions for the design of perpetual pavement in India until the year 2012. However, with the publication of the guidelines by the Indian Roads Congress (IRC37:2012), the design to satisfy 50 year design periods can be adopted with mechanistic pavement design methodology. A comparative study was carried out between four combinations of flexible pavement mentioned in IRC guidelines with perpetual pavement design criteria and proposed rigid pavement on the grounds of sustainability, life cycle cost assessment (LCCA), and carbon dioxide (CO2) emissions. The perpetual pavements were designed by using mechanistic-empirical design software IITPAVE. It is observed that the perpetual flexible pavement becomes a better choice considering the factors like expected design life, economy, and environment.
