Özet

The effect of repeated loading on the cementitious products of lime-stabilized soil is investigated. A stress controlled pneumatic repeated loading device is manufactured for the application of repeated loading. The kaolinite or bentonite is stabilized at optimum amount of lime and are cured for 0, 7 and 28 days. The repeated loading was applied at 1000, 10,000, 100,000 and 1,000,000 cycles at a frequency of 6 Hz. Unconfined compression tests and split tensile tests are conducted on the loaded soil specimens. Strength losses are observed due to the breaking of brittle cement minerals of the lime stabilized kaolinite and bentonite samples at 1000 and 10,000 cycles. However the strength losses are recovered due to densification at 1,000,000 cycles.
