Soil is an imperative aspect in civil construction. Due to poor engineering features, the local soils could lead to a lot of issues in construction and thus, it needs an improvement in their engineering properties. One of the methods of doing this is stabilization that enhances hordes of engineering characteristics including strength, bearing power, compressibility and several other soil properties. Soil Reinforcement is one of these techniques in which we enhance the engineering properties of the matter. This process involves the use of natural fibers to strengthen the soil, and this is an ancient concept. Due to this, the unduly distributed soils that are reinforced with fiber have lured the attention of geotechnical engineers for quite some time now. The pavement performance is a critical aspect in terms of the features of soil upgrade that offers a surface for complete structure of the pavement. This is a matter of great importance, and the strength of pavements gets increased by proper construction & design practices. Tons of fly ash that emerges from hordes of thermal power plants has a low weight, is non-plastic and is extremely fine. This usually gets disposed as a slurry in ponds underlying the area. And if you would have noticed, the ash from these ponds leads to air pollution which is a very serious threat. Since the load-carrying capability of these materials is less, working on their civil engineering properties is quite difficult. However, these material’s performance can be enhanced with the use of methods involving soil reinforcement. For instance, you can employ it as sub-grade to the pavements by employing geotextile sheets for reinforcement. In this case study, certain parts of fly ask compressed to their max dry density with a very little moisture is affixed with the help of Geotextile layers and these even employ the CBR module. In accordance with plan dimension relating CBR module, Geotextile sheets are kept at different preparation of the first, second, third and fourth layers at distinct places. In each fixture of these Geotextile sheets, the value for California Bearing Ratio (CBR) is evaluated in labs and these outcomes are compared with CBR value outcomes that emerged beforehand.
