Analysis of Perpetual Pavement Design Considering Subgrade CBR, Life-Cycle Cost, and CO2 Emissions
The current study aims to evaluate the possibility of perpetual pavement design for the proposed ring road to the City of Pune. Perpetual Pavement concept is relatively new for Indian scenario. In India, national highways are still designed for 15–20 years of service life where as perpetual pavements can provide better service period. The Indian Road Congress guideline (IRC 37:2018) mentions various combinations of pavement design. A comparative study was carried out between proposed pavement design by Pune Metropolitan Region Development Authority and five categories 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 raising California Bearing Ratio of subgrade soil from 10 to 15% with respect to life cycle cost assessment and carbon dioxide emissions. The study analyses whether the improvement in CBR of subgrade has any substantial change in design, cost and CO2 emission of all five combinations of perpetual pavement. IITPAVE software was used to design perpetual pavements. KENPAVE and WESLEA software were used to validate the design. It is observed that the flexible perpetual pavement can be a better alternative considering the factors like expected service period, lifetime cost, and environmental concerns. The study also concludes that positive impact of improved subgrade CBR in terms of overall thickness, life cycle cost, and CO2 emission depends on type of pavement combination used for perpetual pavement design.
