Strength and Durability Characteristics of Stabilised Clayey Soil for Low Volume Roads
Low volume roads play a crucial role in the rural road network since they link rural communities, provide trade networks, and provide access routes for a variety of functions. In this study, fly ash and cement were used to remediate an intermediate plastic clayey soil (CI) in different ratios of designed mix combinations. This soil stabilisation replaces the conventional method with lightly stabilised materials due to their rigidity, homogeneity, and impermeability, making it a practical option for usage on low-volume roads. In this study, the soil was stabilised with varying percentages of cement and fly ash in order to assess its potential for pavement layers. The UCS value increased by 35% from the initial untreated soil in some of the mix combinations. CBR strength, flexural and resilient modulus, and other important mechanical parameters for pavement design were also significantly improved. When compared to the conventional approach, the given mix combinations will save 20% on overall costs. In terms of resistance to wetting and drying cycles, mass loss is linear with durability cycles. Laboratory tests were used to assess the compaction characteristics. The findings concluded that changing existing natural materials can provide good strength and serve as a cost-effective replacement for conventional road construction methods.
