Structural test at the laboratory scale for the utilization of stabilized fine-grained soils in the subgrades of High Speed Rail infrastructures: Experimental aspects

In this paper, this test is experimentally validated. Fatigue performances under biaxial flexion are determined for two stabilized soils. Based on numerical modeling of the HSR structure, results confirm the relevance for a use in HSR capping layers. Moreover, they open new perspectives for scientific and technologic explorations in order to rationalize the costs of the structures.
