Uso de resíduos de construção e demolição em pavimentos de fluxo suave para veículos elétricos superleves

Abstract

The development of new goals for cities and sustainable transportation systems involves a long journey of multiple variables, such as the shift in the energy matrix trend of transportation means, concern about congestion in large urban centers, and the availability of materials and energy for infrastructure implementation. Urban micromobility is a very promising means with high transformative potential, through congestion reduction and low carbon emissions. Given that these are lightweight and super lightweight vehicles, there is a need to adapt road infrastructure, as the loads capable of deforming pavements tend to be smaller. The study aimed to verify the possibility of using construction and demolition waste generated in the municipality of Campo Grande MS in pavements to be used by lightweight vehicles, with the technical premise of achieving minimum parameters determined by DNIT and ABNT regulations. In general, the use of recycled aggregates from Construction and Demolition Waste (CDW) in pavement has proven to be technically feasible, contributing to the promotion of global sustainability, despite any limitations these materials may have, which can be easily overcome through the implementation of quality control processes in their processing.

Keywords: Micromobility, pavements, construction and demolition waste, super lightweight vehicles.
