Title: PERFORMANCE OF TWO GEOTEXTILE REINFORCED SOIL SLOPES
Abstract: In order to build a section of highway SP-123 in Sao Paulo, a 10-meter (33 ft) high geotextile reinforced soil embanlment with a backfill slope of 1h/2v was constructed. The backfill material consisted of a compacted residual soil with a high percentage of fines. Two different reinforcement types with the same unconfined tensile strength were used in the slope construction. In one half of the slope a nonwoven polyester geotextile was used and in the other half a woven polypropylene geotextile. The slope was monitored and its behavior shows satisfactory performance. The results also have shown that the lateral movements were systematically less in the half of the slope length where the nonwoven polyester geotextile was used than in the other half. Analysis of the measured values shows the influence of confinement on the nonwoven geotextile stiffness.
