对南阳某公路路段的未改良膨胀土及改良膨胀土进行对比试验，并对试验结果进行分析，得出结论：随着掺灰率的增加，膨胀土的膨胀率、收缩系数呈现减小的趋势，说明掺石灰可以有效降低膨胀土的胀缩性，并由此确定施工时的最佳掺灰率为6％。

The mechanical testing and the comparative analysis of the test results on a Nanyang highway expansive soil improved by lime and unimproved expansive soil specimens arrived at the following conclu-sions.With the increase of the rate of mixing lime,contraction coefficient and swelling of expansive soils show a decreasing trend.Description mixed lime could reduce the swelling and shrinkage of expansive soils,and thus determined that the optimal rate of mixing lime is 6%.
