..., soil reactivity (shrink–swell index), cyclic wetting and drying, crack intensity, and micro-structure analysis by means of the scanning electron microscopy (SEM) technique. The improvement in swelling potential and swelling pressure was dependent on the rubber content, with polymer–treated mixtures...

.... Five dosage levels of sand and five different thickness of EPS geofoam were investigated in two stages of the experiments. In the first stage of testing, the effect of sand on the swelling pressure of bentonite was investigated by two series of experiments. In the first series of experiments, bentonite...

... of expansive soils that had different physical properties. Four aspect ratios (25, 50, 75, and 100) and five different amounts of fiber (1, 2, 3, 4, and 5%) were used in the study and both swelling pressure and swell potential were evaluated for each combination. The results of the study showed...
