| dc.description.abstract | Soil stabilization using natural fibres is a solution that can have environmental and technical advantages. Among the natural fibres that have adequate characteristics are sisal fibres. In this work, were used sisal fibres to evaluate its potential to improve the characteristics of soils for embankment and road pavement layers construction. Was characterized a clayey sand soil, in its natural state and after mixing it with sisal fibres. The mixture with 0.5%, 1.0% and 1.5% of sisal fibres with 15mm length was characterized and the bearing capacity of the soil was determined using CBR tests (California Bearing Ratio). The results from the tests show that sisal fibre stabilization leads to a decrease, although slight, in the CBR values, for 2.5mm and 5.0mm of penetration. However, when observing the penetration/force curves, the natural soil performed better between 0.0mm and 6.0mm of penetration, suffering a break after 6.0mm, while mixtures with 1.0% and 1.5% of fibres maintained a practically linear progress up to 12mm of penetration. | eng |
| dc.description.abstract | A estabilização de solos com fibras naturais é uma solução que pode trazer vantagens ambientais e técnicas. Entre as fibras naturais que apresentam características adequadas para estabilização de solos estão as fibras de sisal. Neste trabalho foram utilizadas fibras de sisal para avaliar seu potencial em melhorar as características de solos para construção de aterros e camadas de pavimentos rodoviários. Caracterizou-se um solo arenoargiloso, no seu estado natural e após mistura com 0,5%, 1,0% e 1,5% de fibras de sisal com 15mm de comprimento. A capacidade de suporte foi determinada através de ensaios CBR (California Bearing Ratio). Os resultados dos ensaios mostram que a estabilização do solo com fibras de sisal leva a uma diminuição, ainda que ligeira, nos valores de CBR, para 2,5mm e 5,0mm de penetração. Porém, ao observar as curvas penetração/força, constata-se que o solo natural tem melhor desempenho entre 0,0mm e 6,0mm de penetração, sofrendo uma quebra a partir dos 6,0mm, enquanto as misturas com 1,0% e 1,5% de fibras de sisal mantiveram um andamento praticamente linear até 12mm de penetração. | por |
