The cyclic swell-shrink behavior of expansive soils poses formidable challenges to both rigid and flexible structures within pavement engineering, necessitating effective mitigation strategies. This research explores the utilization of waste expanded polystyrene (EPS) beads, a byproduct of hand-crushed EPS blocks, to construct recycled geofoam granules columns (GGC) in expansive soil. The objective is to assess the potential of GGC in mitigating swell-shrink phenomena through rigorous cyclic wetting-drying tests. A series of cyclic swelling-shrinkage experiments were conducted in a purpose-built swell-shrink apparatus, maintaining precise laboratory conditions. Remolded soil samples, incorporating GGC with two distinct diameters (40 mm and 75 mm) and a GGC density of 15 kg/m3, underwent cyclic wetting-drying cycles. The experimental data reveals a consistent reduction in the swell-shrink pattern with an increasing number of applied wet-dry cycles. Notably, the largest diameter GGC exhibited a pronounced decrease in the swell-shrink pattern compared to plain soil. Quantitatively, the findings demonstrate a remarkable 28% and 46% reduction in full swelling for 40D and 75D GGC, respectively, showcasing the efficacy of GGC in countering expansive soil tendencies. Equilibrium conditions were rapidly achieved by the 4th and 5th cycles, leading to a substantial 42% and 53% reduction in time requirements for 40D and 75D GGC. These quantitative assessments underscore the promising application of GGC in pavement engineering, offering a sustainable and technically sound solution to the cyclic swell-shrink challenges. The discussion delves into the mechanisms underlying GGC's influence on controlling swell-shrink behavior, emphasizing the pivotal role of soil-geofoam interaction.
