Study for Aeolian Sand Characteristics by Static Experiment

Abstract:

The representative aeolian sand taken from Horqin desert freeway is used as Subgrade Material. In this paper, California Bearing Ratio (CBR) and rebound modulus E₀ are analyzed by experiments which are based on different aeolian samples with different compaction degree, different dry density and different moisture capacity. Simultaneously, the relation of stress and strain is studied to summarize the mechanical strength characteristic of aeolian sand under different compaction criterion. According to carrying capacity of aeolian sand, statics properties are analyzed. Experiment results show that aeolian sand is compacted under the natural moisture capacity in subgrade engineering, which is feasible and effective. The CBR of the compacted aeolian sand should be controlled less than 10% during construction.
