In case of weak subgrades there are various methods to improve its load bearing capacity, out of which geotextile reinforcement is found to be an effective method. In this study, two types of soils are used as subgrade material and for these soils CBR value is less, so the pavement section is designed as a low volume road section for two cases of traffic volumes; 1 msa and 2 msa. Thickness of each pavement layers were selected according to codal provisions based on CBR values of subgrade material and the pavement sections has been considered for dynamic loading conditions. For the dynamic analysis, Haversine load pulse with a maximum value of 575 kPa and duration of 0.1 s was used. Synthetic and coir geotextiles with different axial stiffness values are used as reinforcing material. Numerical studies were conducted using a Finite Element Analysis program, PLAXIS 2D software. From the analysis it is found that as the axial stiffness increases, vertical compressive strain on subgrade layer and deformation decreases. Pavement sections reinforced with geotextiles placed at different depth from top of surface layer shows better results than unreinforced sections. Reinforcing the pavement section helps to reduce subbase thicknesses and it is beneficial in reducing construction costs. To quantify layer thickness reduction for each reinforced section, the thickness of subbase course changes for remaining layer thicknesses. A modified design chart was prepared based on the test results.
