Abstract
The non-uniformity of the material was evaluated based on the unit area mass, μA*, the initial thickness,h0* and the initial void ratio, e0*, obtained from 400 sheets of non-woven geotextile specimen. Specimens with similar initial conditions were extracted from three different groups. Three kinds of compression test of non-woven geotextile were conducted. The e-logp relationship and coefficients, Cc and Cα, were investigated. In the range of p<100 kN/m2 and t<24 h, these relations and coefficients are influenced by the non-uniformity. On the other hand, in the range of p>100 kN/m2, the effect of non-uniformity becomes
small. In addition, it was shown that void ratio keeps decreasing after t=24 h.
