| Abstract: | The features of the pavement are quite sensitive to the attributes of the sub-grade soil. As a result, the fragile sub-grade is bolstered by embracing the most profitable stabilizing technique. Based on prior research, stabilization with fly-ash enacted sub-grade was identified as a viable option for improving soil quality. In this manner, a test program was attempted to observe the impact of fly-ash stabilization activity on the geotechnical characteristics of poor sub-grade soils. The sub-grade stabilization of soil is one of the most important and important steps in the construction of a pavement. The purpose of this study is to look at the effect of soil mixing with fly-ash on the stability and strength of sub-grade pavements. The soil was amended with various amounts of fly ash, including 9, 18, 27, and 36%. On modified and natural soils, some features such as consistency limitations, CBR, compaction, and UCS tests have been performed. The results of the tests demonstrate that adding fly-ash admixture to the weak soil has a significant impact on its qualitative qualities. It was established that the right percentage of fly-ash is 18 percent, which resulted in significant improvements in soil quality and strength as well as a decrease in swelling and plasticity, and hence this is regarded the best percentage. Plastic Limit (PL), Liquid Limit (LL), Optimum Moisture Content (OMC), Unconfined compressive strength (UCS), Maximum dry density (MDD), and Plasticity Index (Pl) are the beginning values for this study, with the percentage of Fly-Ash included (F.A in percent) in soil sub-grade. The soil stabilized with fly ash is examined using CBR, compaction, specific gravity, sieve analysis, and a water absorption test. Plastic Limit, Liquid Limit, California Bearing Ratio, and Optimum Moisture Content are the properties studied. Based on the findings, it is advised that fly-ash admixture be regarded as a feasible option for the stabilization of fragile sub-grades. |
