The objective of the present study was to evaluate the effects of industrial solid waste (whitewash mud) on geotechnical properties considering the following engineering parameters: California Bearing Ratio (CBR), Atterberg limits and Permeability test. Seven soil samples derived from Alagoinhas, Bahia - Brazil, were classified by the Transportation Research Board (TRB) system. Two were selected as having a great geotecnical potential classified as A-3 (0) and A-2-4 (0), whitewash mud contents 10%, 15%, 20% and 25% dry weight and medium compaction effort were studied in the laboratory testing program. The results indicated the soil denominated good gravel as being the most promising one, when stabilized with whitewash mud, reaching the best results with the dosage of 20 and 25% of whitewash mud.
O objetivo do presente estudo foi avaliar os efeitos do resíduo sólido industrial (lama-de-cal) nas propriedades geotécnicas de amostras de solo da região de Alagoinhas, BA, Brasil. Das sete amostras coletadas, apenas duas foram selecionadas, por apresentar maior potencial geotécnico. Utilizaram-se ensaios de caracterização, CBR e permeabilidade, cujos resultados indicaram que a amostra de solo denominada good gravel quando estabilizada com lama-de-cal, na dosagem de 20 e 25%, foi a mais promissora.
