Road Performance of Lusheng-Cement Composite Stabilized Waste Soil
Adding Lusheng material,the specimen of Lusheng-cement composite stabilized waste soil(Lusheng-cement soil)was prepared to test its unconfined compressive strength,elastic modulus,flexural tensile strength,and fatigue life.Corresponding tests were conducted for the cement stabilized waste soil(cement soil),and the test results were compared and analyzed.The study results showed that the Lusheng material could effectively improve cement soil's unconfined compressive strength,elastic modulus,and flexural tensile strength,and the improvement effect of the unconfined compressive strength increased with age.Under the same stress,the Lusheng material could greatly improve the fatigue life of cement soil.Compared with cement soil,the freeze-thaw cycle had a small effect on the Lusheng-cement soil,because the Lusheng material strengthened the connection between particles inside the cement soil in the freeze-thaw cycle.At the same time level,the shrinkage deformation of Lusheng-cement soil was the smallest,indicating that the Lusheng material can reduce the shrinkage amount of cement soil.
