...K. Y. Li; X. W. Tang; M. L. Fei; J. Chou; X. L. Chen; Q. Q. Xiang; T. Q. Wang During their service life, needle-punched nonwoven geotextiles are frequently subjected to uniaxial tensile strains, which may impact their permeability behavior. The basic model of the permeability coefficient...

... and retention performances of various soil-geotextile systems were studied. Nonwoven geotextiles were numerically modelled, partly by using the Poisson line process to simulate the inherent randomness found in fabricated nonwoven filters. The model results were compared with laboratory tests to corroborate...

... filter core (referred to as DPRF) is proposed. This paper studied the drainage characteristics of DPRF wrapped with a woven geotextile and traditional drainage pipes wrapped with a nonwoven geotextile (referred to as DPNG) in fine tailings sands with a reduced scale model test. The results showed...

...A. Abbaspour; B. F. Tanyu; A. H. Aydilek; A. Y. Dayioglu Long-term filtration tests were conducted to assess the hydraulic compatibility of the recycled concrete aggregate (RCA) and nonwoven geotextile that is typically used in underdrains. The RCA samples used in this study were collected from...

...J. N. Thuo; K. H. Yang; C. C. Huang The use of nonwoven geotextile drains in geosynthetic-reinforced soil (GRS) structures has been suggested to facilitate the dissipation of pore water pressure. It has also been recognised that the nonwoven geotextile may retard water penetration due...

...M.-H. Li; R. B. Gilbert This note is intended to provide insight into the cause of post-peak strength reductions for textured geomembrane–nonwoven geotextile interfaces. Direct shear tests were conducted with incremental displacements, where one of the two interface materials was replaced, and also...

...A. H. Aydilek; T. B. Edil A study of the filtration behaviour of contaminated wastewater treatment sludges was conducted. The laboratory portion of the study included a series of filtration tests with different nonwoven geotextiles. Filtration performance of the sludge–nonwoven-geotextile systems...
