...S. Srivastava; U. Balunaini Moisture infiltration into expansive subgrades induces differential swell pressures, leading to surface heave, cracking, and deterioration of pavement serviceability. To replicate this behavior, extensive large-scale model experiments were conducted in a 1.5 m × 1.5 m...

...S. Srivastava; U. Balunaini This study evaluates the performance of model pavements constructed in a 1.5 m × 1.5 m × 1.1 m test chamber under differential swell pressure induced by expansive subgrades. Three configurations were tested− one with a 400 mm Wet Mix Macadam (WMM) layer directly over...
