- Soil stabilization with sisal fibresPublication . Luzia, Rosa; Gardete, Dinis; Diogo MonteiroSoil 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.
