Abstract: The expansive soils at Yicheng-Baokang section of Mazhu highway were studied in this paper.  Soil improvement by lime was included in a parallel study. Through heavy compaction test, Califonia Bearing Ratio (CBR) test and swellshrink test, the variation of compaction properties, CBR value and total swell-shrink ratio of swell soil mixed with different ratios of lime were studied. Based on these, the optimal ratio of lime for improving the expansive soil in the region was determined.

Key words: Expansive Soils, Soil Improvement, Lime-treated Test
