“…Hence, as compared to chemical stabilization of soil using raw materials such as cement/ lime, FA-based geopolymer stabilization of soil would be relatively inexpensive [41]. Moreover, the use of geosynthetics, such as geotextiles for reinforcements have also been referred to as "cost-effective" by many authors in the past [43,44]. Hu et al [43] in particular stated that the utilization of Geosynthetic reinforcement in structures such as bridge abutments is more economical compared to the use of conventional reinforced concrete, due to the shorter construction period and cheaper raw materials such as geotextiles.…”

Soils in their natural form are often deemed unsatisfactory to be directly used as a construction material for their respective applications. Under such circumtances, employment of ground improvement techniques to better suit the soil for its function is typically the most economical approach. Consequently, the present research investigated into the beneficial effect of modernized soil treatment techniques, i.e., geopolymer stabilization using fly ash as the precursor and geotextile reinforcement, on the strength enhancement of natural residual soil. A series of unconsolidated undrained (UU) triaxial compression tests were carried out to assess variation of geopolymer stabilized residual soil strength based on the varying number of geotextile layers, geotextile arrangement, and confining pressures. It was found that the increase in the number of geotextile layers resulted in a corresponding rise in soil strength and stiffness. It was also discovered that placement of geotextile layers at sample regions which suffered the maximum tensile stress-strain during loading was more effective compared to random placement. Soil strength was observed to reduce with increasing confining pressure which demonstrated the effectiveness of utilizing geotextile reinforcement at greater depths below the ground to be less. Failure patterns showed that while unreinforced soil resulted in failure along a shear plane at an approximate angle of 45 + φ/2 (φ: angle of internal friction), reinforced samples demonstrated a bulging failure where the soil between adjacent layers of geotextiles appeared to bulge. The findings deemed the employment of geopolymer stabilization and geotextile reinforcement on natural residual soil very effective with regards to the enhancement of soil strength and stiffness.

“…Very high alkalinity could affect geo-textiles made from certain polymers. The most important external influence is UV radiation, which can significantly degrade synthetic materials within months, if not weeks [3] You-Chang Hu et al [4] focused to determine the effects of the vertical spacing of the reinforcement and the relative compaction of the granular soil on the performance of the geo-textile reinforced soil mass and was concluded that the compressive strength of geo-textile reinforced soil increases significantly with the decrease in reinforcement spacing or with the increase in the degree of the relative compaction of fill. Kuo-Hsin Yang et al [5] showed that the shear strength of reinforced clay increased as the number of geo-textile layers was increased.…”

Geo-textiles are polymers of high tensile strength, and they are flexible in nature. They are widely used in a variety of engineering applications including soil reinforcement. Hence, it was necessary to make an in depth study on the use of geo-textiles and their relative advantages. This work focuses on a comparative study on the load carrying capacities using geo-textiles. A series of California Bearing Ratio (CBR) tests were performed on soil reinforced with geo-textiles, placed in single and double layers at different depths. The CBR value and stress-strain results of this study provided a better understanding on the comparative changes in load carrying capacities of the soil. The information will help in better decision making in the field of soil reinforcement.
