Life Cycle Sustainability Assessment of Flexible and Rigid Pavement Designs: A Case Study of Illinois Interstate Highway

The Illinois Tollway Authority reconstructed a 14-mile section of Interstate 90 highway from Schaumburg to Elgin (IL, USA). The reconstructed pavement section consisted of a jointed concrete pavement with a recycled aggregate subbase. The existing pavement was milled and crushed on-site and used as an aggregate subbase. This study is performed to assess the sustainability of this pavement and compare it with that uses virgin aggregate subbase and that consists of full-depth asphalt pavement with similar recycled subbase. The triple bottom line framework of sustainability is used to evaluate which of the three alternate pavement options is more sustainable. Life cycle assessment is used to calculate the environmental impacts, economic sustainability is assessed by performing life cycle cost analysis, and social sustainability is assessed by designing a public survey using Social Sustainability Evaluation Matrix (SSEM). Finally, the triple bottom line results were integrated to calculate the sustainability index using the Integrated Value Model for Sustainable Assessment (MIVES) method. Overall, the results revealed that the jointed concrete pavement with recycled subbase has the highest sustainability index.
