Caracterização e classificação de solos típicos do Recôncavo Baiano para fins rodoviários

Abstract

This study analyzed the suitability of three soils typical of the Recôncavo Baiano for use in structural layers of road pavements. Chemical analysis tests, compaction in normal Proctor energy, California support index and TRB, MCT and Resilient classifications were performed. Finally, the behaviors indicated in each classification were correlated with the type of clay found in the fine fraction of each soil. The results obtained indicate that the MCT classification is the most appropriate, as it takes into account mechanical and hydraulic parameters of the soils and that the type of clay is determinant in the behavior of the soil. Two of the three soils studied showed satisfactory results, allowing the use of locally occurring soils as low-cost pavement layers.
