Triaxial Test on the Construction-Aid Soil Stabilizer in Stabilizing Fine-Grained Soil

Abstract

Based on the airport pavement construction features and utilization requirements, we stabilize the fine-grained soil in Jining district of Shandong province by using the construction-aid (con-aid) soil stabilizer.We test the stress-strain curve and Mohr failure envelope of the triaxial shear of the fine-grained soil before and after being stabilized under various confining pressure by using the unconsolidated-undrained (UU) triaxial test method. We also analyze the change rules of the cohesive force Cu and internal friction angle φu to evaluate the effect of stabilizing fine-grained soil by using the con-aid soil stabilizer. In addition, we discuss the feasibility of applying the stabilizer in constructing the airport pavement and roads.
