| Abstract: | The characteristics of the pavement are quite sensitive to the characteristics of the subgrade soil. Therefore, the unstable sub-grade is strengthened by utilizing the most lucrative stabilizing procedure available to it. As a result of previous study, it was determined that stabilization with fly-ash at sub-grade was a feasible approach for enhancing soil quality. An attempt was made in this manner to observe the impact of fly-ash stabilization activity on the geotechnical features of poor subgrade soils through the use of a testing program. The stabilization of the soil beneath a pavement is one of the most significant and time-consuming processes in the construction of a pavement. For the purposes of this investigation, the influence of soil mixing with fly-ash on the stability and strength of subgrade pavements is being investigated. Different levels of fly ash were added to the soil to improve its fertility, including 9, 18, 27, and 36 percent. Some soil characteristics, such as consistency restrictions, CBR, compaction, and UCS testing, have been investigated on both modified and natural soils. Adding fly-ash admixture to a weak soil, according to the results of the studies, has a substantial impact on the soil's qualitative features. This percentage has been determined to be 18 percent, which has been shown to result in considerable increases in soil quality and strength, as well as a reduction in soil swelling and plasticity. This number is therefore considered to be the optimal percentage. With the percentage of Fly-Ash included in the soil sub-grade (F.A in percent) as the starting point for this study, the following parameters are determined: Plastic Limit (PL), Liquid Limit (LL), Optimum Moisture Content (OMC), Unconfined compressive strength (UCS), Maximum dry density (MDD), and Plasticity Index (PL). It is determined whether the soil has been stabilized by fly ash by performing CBR, compaction, specific gravity, sieve analysis, and a water absorption test on it. The parameters investigated include the Plastic Limit, the Liquid Limit, the California Bearing Ratio, and the Optimum Moisture Content. A realistic approach for stabilizing unstable sub-grades, according to the findings, is to incorporate fly-ash additive into the concrete mix. |
