| Summary: | In Colombia, it is common to use different types of conventional pavements, such as rigid, flexible, and articulated pavements, to address the challenges of mobility and connectivity throughout the country. However, these options are not always the most suitable for the specific conditions of each project. Unlike conventional pavements, which have a lifespan of 20 to 30 years, Perpetual Pavements (PPs) are designed to function satisfactorily for 50 to 70 years without requiring major maintenance and rehabilitation work. This makes them a more environmentally and economically viable option compared to conventional rigid pavements (CRP), conventional flexible pavements (CFP), and cobblestone pavements. However, in Colombia, there is a limited amount of research addressing perpetual pavements. Therefore, this study focused on evaluating and comparing the environmental burden and associated costs of four pavement structures (CRP, CFP, PP, and ICP) using life cycle assessment (LCA) and life cycle cost assessment (LCCA) methodologies. To carry out the environmental analysis, SimaPro software was used to collect input data and evaluate the associated environmental burdens. Regarding the economic analysis, Net Present Value (NPV) was used as a financial indicator to assess costs in the project's starting year. The research results demonstrated that perpetual pavements have a lower environmental burden and lower costs over their 50-year lifespan compared to conventional pavement alternatives. |
