Estimating Mechanistic Parameters for Subgrade Using Gyratory Compaction with Pressure Distribution Analyzer
AbstractCompaction control for pavement foundations typically consists of determining the optimum water content and maximum dry unit weight from a Proctor test, and then specifies an acceptable water content and dry unit weight range in the field. Although this has become a widely accepted approach, it cannot provide the mechanistic parameters of the compacted structures. The purpose of this study is to examine the application for using gyratory compaction with an integrated pressure distribution analyzer (PDA) sensor kit for determining mechanistic compaction parameters that could be used to more directly support mechanistic-based earthwork compaction control. Correlations results are presented that link the moisture-density-undrained shear strength/resilient modulus of the gyratory-compacted specimens for loess (primarily silt) and glacial till (lean clay) embankment materials.
