| Abstract | The use of geotextiles is spreading rapidly because of its ability to stabilize and improve unstable soil structures. When geotextiles are used to perform the functions ofdrainage, separation or reinforcement, the interface_may act as a weak plane or a potential failure plane. In order to investigate the interface behavior beween the soil and geotextiles, laboratory experiments were carried out using a direct shear apparatus. Geotextile samples were placed between laterite which was compacted using a newly designed miniature Proctor hammer. A total of twenty-four direct shear tests were conducted on the soil with and without geotextiles. Results from this direct shear testing program show pronounced changes in the interface behavior. The experimental findings can be summarized as follows: i) A 35 to 60% reduction in shear strength is observed when the geotextile is used under both drained and undrained shearing conditions. ii) In the drained tests, there is no apparent change in the volumetric behavior with respect to the consolidation stress. iii) The effective stress path in the undrained condition is highly dependent on the creep effects of the geotextile. |
