AbstractThe change of climate gives fluctuation of water content in its result rain, evaporation, rising water ground level and evapotranspiration. The expansive soil will volume change and suction. This behavior can damage on construction structures especially, roads and light building. The phenomenon is very interesting to be researched, how far the effect of water content change and variation suction toward the behavior volumetric swelling expansive soil. This paper presents results of measurement of swell percent, water content and total and matric suction under gradual and controlled moisture intake using dial gages and filter paper .It was found that the suction decreases with increase water content. The results showed that the greater swelling the smaller total and matric suction. The study showed that approximately a linear relationship between the suction with water content.
