Research on Static and Dynamic Characteristics of Aeolian Sand in Keerqin Desert Area
Quality subgrade filler is scarce in highway construction in the desert area. Aeolian sand is selected as a subgrade filler. The basic physical properties and influence law of static mechanical index of resilient modulus, CBR of aeolian sand affected by moisture content ratio, dry density, compactness are analyzed and studied. Empirical formulas are derived between CBR, resilient modulus and water content ratio, compactness by mathematical statistical methods. The variation regularities of dynamic compaction characteristics - which are influenced by test methods, vibration time, the way of filling, and water content ratio - are researched simultaneously. The results can provide guidance for construction and control of highway in this region.
