This study investigates the compression behaviour of structured clay under one-dimensional loading, focusing on the onset and extent of transitional behaviour as governed by clay ped size and fibre inclusion. Three small, medium, and large ped sizes were prepared to interpret aggregation's role in modifying compression responses. Specimens containing polypropylene fibres were evaluated in a separate series to determine how reinforcement affects the progression from structured to remoulded states. Experimental findings indicate that medium ped specimens consistently exhibit non-transitional behaviour, aligning directly with an established compression path. Conversely, small and large ped specimens demonstrate partial-transitional behaviour, featuring a measurable, though incomplete shift before converging with the reference compression line. Volumetric strain convergence assessments reveal that, while all ped sizes ultimately arrive at a comparable compression state, small and large ped specimens maintain partial-transitional tendencies at mid-loading stages. Fibre-reinforced specimens show an earlier onset of non-transitional behaviour than those with natural ped structures, suggesting that fibre-induced heterogeneity accelerated the breakdown of soil fabric. A newly formulated destructuring function is established, quantifying the progressive collapse by correlating changes in compressibility parameters to stress-induced structural degradation.
