“…However, for some roads built on soft ground, the weight load on the road foundation will also increase as the pavement will be thicker by repair. In this way, the repeated repair and paving of the same road will not only make the road unable to pass normally but also the repair and maintenance costs that need to be spent is increasing 4),5), 7) . From these situations, it is impotant that the upper load of the road foundation to avoid road residual settlement is reduced.…”

As roads often have a residual settlement on soft foundations, reducing the weight of the subbase course is an alternative way to solve this problem.In this study, the strength and deformation characteristics of artificial lightweight subbase course material under monotonic and cyclic loading were discussed. The specimens in the dry and optimum moisture content condition were applied cyclic loading by 10,000 cycles under three confining pressures (29.4, 49.0, and 68.6 kPa), and then the effects of cyclic loading on the strength and deformation were discussed. From the test results, it was found that the shear strength of the specimens after cyclic loading decreased in the dry condition, while the shear strength of the specimens after cyclic loading was basically unchanged in the optimum moisture content condition. And it is considered that the deformation modulus of specimens after cyclic loading increased in both conditions.
