one of the methods for the improvement of soil against the tensile stresses is using the artificial supplements in soil such as metal belts or nets, polymer materials and natural fibers. technically this method is called the reinforced of soil.  when a pavement is located on soft soil, great deformations can occur as a result of the crossing of traffic load in superstructure layers of the body....

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 ...

conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...

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 was also observed in field test cells by exhuming geotextile samples from the cells after exposure followed by analysis. The ...

Nonwoven geotextiles are commonly used in filtration applications. For some applications, however, a nonwoven geotextile filter may not have the required mechanical properties to withstand deformations, and an additional woven geotextile is usually employed in design. While reinforcement is an important function expected from these two-layer geotextile systems, filtration is another function th...

The design of geotextile containers for dewatering applications typically requires hydraulic compatibility between the geotextile and the confined fill material. Ideally, a geotextile container must successfully retain the solid phase of the fill material and must not be clogged during the dewatering process. This becomes difficult to achieve when the fill material is fine grained and the pore ...

Dynamic behavior of soil are evaluated relative to a number of factors including: strain level, density, number of cycles, material type, fine content, geosynthetic inclusion, saturation, and effective stress .This paper investigate the dynamic behavior of saturated reinforced sand under cyclic stress condition. The cyclic triaxial tests are conducted on remolded specimens under various CSR whi...

Threats to beaches have accelerated the coastal destruction. In recent decades, geotextile tubes were used around the world to prevent coastal erosion, to encourage beach nourishment, and to assist mangrove rehabilitation. However, the applications of geotextile tube in sandy and muddy coasts have different concerns as the geological settings are different. Applications of geotextile tubes in s...
