The instability of railway tracks including mud pumping, ballast degradation, and differential settlement on weak subgrade soils occurs due to cyclic stress from heavy haul trains. Although geotextiles are currently being used as a separator in highway embankments, their ability prevent the migration fine particles reduce pore pressure has be investigated under adverse hydraulic conditions subs...

Applications of geotextiles within tertiary stormwater treatment systems and for stormwater infiltration can provide a substrate for biofilm formation, enabling biological treatment of contaminants. Geotextiles can serve as an efficient part of stormwater filtration within the urban water environment. The project assessed the applications of three experimental granular filters as a sustainable ...

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...

Due to the ever-growing demand for bast fibres technical and garment textiles, complementary sources textile flax, whose cultivation in western Europe cannot really be extended, need proposed. In this study, interest harvesting processing linseed flax straw is studied geotextile applications. The main critical stages of fibre-to-yarn production geotextiles were investigated. Different dew retti...

Understanding the load transfer mechanism can support engineers having more economical design of geosynthetic reinforced piled embankments. This study aims to investigate mechanisms by two different numerical methods including Discrete Element Method (DEM) and Finite Difference (FDM). The DEM model adopts (a) discrete particles simulate micro-structure granular materials (b) coupled element – f...
