In constructing embankments with cohesive soil, nonwoven geotextile is frequently used. Authors examined on the applicability of geotextile to horizontal drainage, obtained main conclusions are as follows.(1) The more dry unit weight is, the higher hydraulic capacity in low confining stress condition is, and the more a decreasing value of transmissivity is.(2) In evaluating of transmissivity by conducting laboratory test, some decreasing condition should be considered, for example confining stress, clogging and so on.(3) Nonwoven geotextile has sufficient durability.
