Improvement of Subgrade Strength with the Use of Geotextiles—A Case Study
The structure of the pavement is formed upon the subgrade of soil, which can be either the natural surface or a surface that has been prepared. It offers the pavement layers the necessary support and evenly distributes the load that the traffic produces on the surface to the layers beneath it. To ensure the pavement structure will continue to function effectively over time, it is imperative that the subgrade soil possesses both strength and stability. In order to assess the qualities of the subgrade soil, a number of tests are carried out, and then, the right actions are taken in order to improve its strength and stability. These actions include enhancing the soil quality, ensuring adequate drainage, and making use of geosynthetic materials. The purpose of this investigation was to determine the effect that reinforcement material has on the level of strength possessed by the subgrade soil. The efficiency of geotextile as a reinforcing material was determined by carrying out California Bearing Ratio (CBR) experiments on soil samples with and without geotextile reinforcement, under both soaked and unsoaked conditions. These tests were carried out in order to compare the results of the two groups. The study utilized both woven and non-woven geotextile materials in order to evaluate the effects of varying the depth of the geotextile layers as well as the number of layers on the strength of the subgrade soil. In order to conduct the tests, several combinations were formed by inserting one, two, or three layers of woven and non-woven geotextile at varying depths into the soil samples. The placement of two layers of geotextile at depths of H/5 and H/2 from the top produced the best possible results. Here, H represents the overall height of the sample. In addition, it was discovered that the strength of the samples that were treated with woven geotextile increased much more than that of the samples that were treated with non-woven geotextile. In addition to determining which method is the most efficient for stabilizing the soil, a cost comparison of constructing roads without geotextile reinforcement versus constructing roads with a lower thickness of pavement and geotextile reinforcement was carried out for both rural and urban highways. This comparison was made in terms of the amount of money required. According to the findings of the cost analysis, incorporating geotextile in soil samples has the potential to significantly cut construction costs. This has the potential to result in cost reductions of roughly 12.39% and 22.78% of the total cost of pavement per kilometer for urban and rural roads, respectively.
