Electrical resistivity for non-destructive durability assessment of stabilized soils under drying-wetting cycles
Long-term durability of chemically stabilized soils under repeated drying-wetting (D-W) cycles is a critical concern in geotechnical engineering, but conventional durability assessment relies on destructive mechanical testing, which prevents continuous monitoring of the same specimen. This study…
