O presente estudo investigou a utilização de rejeitos de minério de ferro (RMF) como substituto do agregado miúdo na produção de pavimentos intertravados, com o intuito de promover soluções de baixo impacto ambiental e alinhadas aos princípios da economia circular na construção civil. Os blocos foram produzidos sem a adição de aditivos ou plastificantes, e as propriedades físicas e químicas do RMF foram analisadas. Os resultados demonstraram que a resistência à compressão dos pavimentos aumentou conforme a variação no teor de umidade e na relação agregados/cimento. Além disso, os ensaios de lixiviação indicaram que os blocos atendem aos limites estabelecidos pela NBR 10004 para a segurança ambiental. Diante desse contexto, a pesquisa contribui para o desenvolvimento de alternativas de baixo impacto ambiental no setor da construção ao demonstrar a viabilidade do aproveitamento de resíduos industriais como matéria-prima para materiais de pavimentação.
