<![CDATA[Conventional geotextile material has been widely used, however, the application of geotextile installation for soft soil improvement in certain areas has become expensive due to poor transportation systems. In response to this, researchers have endeavored to develop an alternative stabilization material by weaving strips (plastic webbing or PW) derived from waste mineral water bottles into a geotextile for soil reinforcement. This initiative aims to investigate the alterations in the field California Bearing Ratio (CBR) values—assessed through laboratory-scaled model tests—of subgrade soils both in their untreated state and when reinforced with the proposed geotextile. The outcomes of the laboratory model field CBR tests demonstrate that the incorporation of geotextile reinforcement exerts a discernible influence on the CBR values of the subgrade soil. Specifically, for a penetration depth of 2.5 mm, the CBR value of the unreinforced subgrade soil was recorded at 8.30%. This value exhibited a tendency to increase by 2.74% when reinforced with geotextile strips of 0.5 cm width, yielding a CBR of 11.04%, and by 4.74% with geotextile strips of 1.5 cm width, resulting in a CBR of 13.04%. Similarly, at a penetration depth of 5.0 mm, the CBR of the unreinforced soil was 10.07%, which increased by 1.48% with the addition of 0.5 cm-wide geotextile strips (11.55%) and by 1.03% with 1.5 cm-wide strips (11.10%). Integration of geotextile reinforcement significantly influences the CBR values, thereby contributing to the improvement and enhancement of otherwise low subgrade soil CBR characteristics.]]>
