Abstract: Soil is enough powerful in compression and relatively weak in tension. To increase stability and reduce deformation tensile elements are inserted into the soil as part of the soil reinforcement.The primary purpose of the geotextiles, which are used as reinforcement, is to give soil tensile strength at a strain level consistent with the functionality of the soil structure. Geotextiles are employed as reinforcement in paved roads, railway tracks, earth retaining walls, mining subsidence protection, and embankments of shallow weak soils. This study describes the assessment to analyze the properties of soil, the geotextile-soil characteristics due to direct shear test. Also, to study the CBR values at 2.5mm and 5mm penetration in soil system without and with geotextile (woven and non-woven) layer at the interface of the two soil layers. Four types of geotextiles are used (two woven and two non-woven geotextiles). Geotextiles are placed at H/3 height from the bottom of the CBR mould. The results show an increase in the CBR values of the unreinforced soil and there is an increase of 28.12% and 44.6% in case of non-woven and woven geotextiles, respectively at 2.5mm penetration and 3.46% and 9.64% in case of 5mm penetration. The result also shows percentage decrease in thickness of 10.136% and 3.74% in the flexible pavement with the inclusion of woven and non-woven geotextiles, respectively.
