pavimentação, resíduo, sub-baseAbstract
Analisar misturas de solo com adições de Resíduos da Construção Civil (RCC) visando o seu aproveitamento na pavimentação rodoviária é meta relevante na configuração tecnológica atual, visto que essa atividade absorve grandes quantidades de insumos. Nesta pesquisa, analisa-se três misturas de solo-RCC, sendo: 100% solo; 30% RCC + 70% solo; e 50% RCC + 50% solo. Foram ensaiados somente osmateriais na fração miúda (passante na peneira nº 4). Como trabalho experimental, foram realizados ensaios de caracterização física dos materiais e caracterização mecânica das amostras através do Índice de Suporte Califórnia (ISC) com medição de expansão, que expuseram a qualidade e a potencialidade de cada mistura. Conclui-se com os resultados laboratoriais a adequação da amostra de 50% RCC + 50% solo em sub-base de pavimentos de acordo com a NBR ABNT 15.115 (2004)
