The purpose of this work is to assess and develop experimental techniques that allowwicking measurement over a wide range of textiles. Various kinds of fabrics, nonwoven layers and anelectro spinning nylon layer were used as the test materials. A syringe is used to drop a 0.02 g spot ofdistilled water on the sample and a digital camera to take pictures simultaneously. When the wickingprocess st...

The paper presents the effect of using cashew nut shell liquid (CNSL), a low-priced agro by-product and renewable resource, to treat coir geotextiles. Large-scale direct shear tests were performed on sands reinforced with untreated treated geotextiles at different normal stresses (50 kPa, 100 150 kPa). Sands three particle sizes (coarse, medium, fine) used for study. strength parameters soil sa...

This paper tries to study the effect of geosynthetic inclusion on the improvement of the load-settlement characters of two layered soil. In addition, the effect of geogrid and geotextile in reduction of the required thickness of subbase layer in unpaved roads is studied. Considering the vast application of bearing ratio tests in road construction projects, this test is used in present investiga...
