Owing to the alternating processes of rainfall and evaporation, compacted loess employed in ground roadbed construction frequently experiences drying wetting (D-W) cycles. These cycles are prone induce substantial deformation soil mass, posing a risk integrity buildings infrastructure. Consequently, this study delved into effects D-W on behavior loess, considering varying initial dry densities water contents. To achieve profound understanding characteristics we meticulously monitored resistivity ratio, crack microstructure throughout tests. Furthermore, constitutive model was developed forecast under The findings revealed that both vertical strain ratio exhibited an upward trend with increase cycle numbers, while they downward as density increased. Notably, content identified significant factor affecting ratio. Additionally, occurrence progression cracks led slight particle abundance proportion total pore area. Meanwhile, during process, infiltration softened cementing substances, resulting disruption connections between aggregates. This made it much easier for expand after sample dried. constructed by incorporating yield surfaces account decreasing increasing validity proposed substantiated through comparative analysis measured calculated data. comprehensive investigation furnishes theoretical foundation assessing stability roadbeds subjected
