dc.description.abstractErosion behavior at the interface of different layers is a critical consideration in pavement design and construction. Especially, this issue poses a particular challenge in dispersive clays, which are prone to excessive erosion. The current paper focuses on evaluating the effectiveness of nanoclay in stabilizing and mitigating the contact erosion behavior of dispersive clays. To do so, a range of experimental testing, including double hydrometer, pinhole, contact erosion and unconfined compressive strength (UCS) tests was employed. The findings revealed that incorporating 0.75% nanoclay content yielded significant results, leading to a remarkable 391% increase in the UCS, a notable 58% reduction in dispersivity potential (DP), a 53% decrease in eroded soil mass, and a 29% decrease in the dispersive clay settlement after a 28-day curing period. Additionally, new exponential correlations were successfully developed between soil dispersivity and contact erosion parameters (CEPs) with high coefficients of determination using over 50 contact erosion test results. To facilitate the estimation of CEPs, the values were made dimensionless including the ratios of eroded soil mass (m/m0), settlement (S/H), and void ratio (ef-e0/e0). Finally, scanning electron microscopy (SEM) and microstructural image processing (MIP) confirmed the filling between soil particles and the reduction of the number of voids due to nanoclay incorporation into dispersive clays.en_US
