The paper researches the compressive strength of lime and bentonite mixture by a compaction test and unconfined compressive strength test, and determines the compaction curves and unconfined compressive strength value of the mixture with different lime content. The test obtains the maximum dry density of 1.41 g/cm3, 1.35 g/cm3, 1.303 g/cm3 and 1.261 g/cm3, optimum moisture contents of 22.9 %, 24.1 %, 25.2 % and 26%, and unconfined compressive strength values of 198.2 kPa, 222.7 kPa, 256.2 kPa and 285.6 kPa for the four mixture with different lime content of 0%, 5%, 10%and 15%. The test shows that with the increase of lime content, the unconfined compressive strength value is increasing.
