The swelling characteristics of a mixture of waste EPS particles and expansive soil are influenced significantly by initial water content. In order to search out the influential regularities under different initial water content, the tests of swelling ratio without pressure, swelling ratio under pressure and swelling force are conducted. The experiments result in valuable conclusions as fol-lows. First of all, the swelling ratio without pressure and swelling ratio under pressure of the mixture increase gradually in the process of absorbing water and saturating, and swelling curves have experienced the following three stages: rapid expansion, slow expansion and stable period. Fur-thermore, the smaller initial water content is, the shorter rapid expansion period continues and the faster the swelling rate becomes. What's more, the experimental data demonstrate a linear negative correlation between swelling ratio (without pressure or under pressure) and the initial water content. The expansive force changing with the initial water content is nonlinear, reached the maximum when the initial water content is close to the optimum moisture content.
