Accelerated Loading Evaluation of Subbase Layers in Pavement Performance, Technical Summary
The mighty Mississippi River formed and sculpted most of south Louisiana, creating large areas of alluvial deposits consisting of soft, wet, and unconsolidated soil layers. Many Louisiana pavements were built in these areas of naturally low shear strength and minimum bearing capacity. Louisiana's wet climate (over 50 inches of rain per year) combined with the soft alluvial fine-grained soils exacerbate the potential for moisture sensitivity and bearing capacity problems. This leads to both construction and performance problems in the long term, often exemplified by detrimental pumping of the wet subgrade under repeated traffic loads. In some cases, initial construction on wet subgrade soils is often difficult because working table conditions may not exist naturally.
