Abstract
The concrete pavements at Kualakai Parkway have been experiencing differential lateral and horizontal movements. One of the many possibilities to explain this is the fact that the foundation soils are collapsible soils. A boring was drilled to collect soil samples in the median and a variety of tests were conducted to determine its collapse potential. Index tests of the fine-grained soils were used to characterize the soil properties such as moisture content, Atterberg limits, Unified Soil Classification System group names and symbols, and specific gravity. Mineralogically, the soil elements present were identified using scanning electron microscopy (SEM) with both energy dispersive spectroscopy (EDS) and wave dispersive spectroscopy (WDS) analyses and crystalline phases of the soil were identified using X-ray Diffraction (XRD). Mechanical properties were then characterized using the double oedometer procedure.
