چکیده
Abstract Geosynthetics are human made material used to reinforce soils improve the bearing capacity and permeability of soil, reducing soil settlement. application plays a vital role in highways constructions with no additive layers, such as cement concrete, asphalt or subgrade layer that affects unbounded layers. This paper presents geosynthetics tensional has been for reinforcement clayey soil. Laboratory California ratio (CBR) test samples were prepared soils. Clayey containing unreinforced reinforced The sample comprised thermally bonded nonwoven geotextiles (NW) superior needle-punched (SNW) different characteristics (NW 8, 10, 21, 30 SNW 14, 25, 62, 75) three-layered, based on materials perform defined tests. These tests show that, increases.

Long-term filtration performance of nonwoven geotextile-sludge systems
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 ...
متن کاملResistance of a nonwoven geotextile against mechanical damage and abrasion
The installation procedures (which induce mechanical damage) and abrasion can cause unwanted changes on the properties of the geotextiles. In this work, a nonwoven polypropylene geotextile was subjected to three degradation tests: (1) mechanical damage, (2) abrasion and (3) mechanical damage followed by abrasion (successive exposure). The damage caused by the degradation tests was evaluated by ...
متن کاملField Performance of Geotextile Reinforced Sludge Caps
Geosynthetic reinforced capping of highwater content waste materials is becoming an efficient and economic way of dealing with the confinement of the contaminants. To define the filtration performance of sludge-geotextile systems and investigate their durability, ten sludge lagoon test cells were constructed using of a lightweight fill, i.e. a wood chip/soil mixture over different geotextiles. ...
متن کاملCBR Improvement of Clayey Soil with Geo-grid Reinforcement
The quality and life of pavement is greatly affected by the type of sub-grade, sub base and base course materials. The most important of these are the type and quality of sub-grade soil. But in India most of the flexible pavements are need to be constructed over weak and problematic sub-grade. The California bearing ratio (CBR) of these sub-grade have very low, it needs to more thickness of pav...
متن کاملInvestigation of Geotextile Yarn Effects on Improvement of Long-Term Deformation of Sandy Soil
Accurate predictions of the amount and the rate of long- term deformation of reinforced soils under an applied load are important key issue in geotechnical engineering, in which the deformation of soil develops with time at a state of constant effective stress. Since geosynthetic is generally considered creep sensitive therefore, evaluation of creep behavior of geosynthetic reinforced soil (GRS...
