IMPROVING EMBANKMENT DESIGN AND PERFORMANCE: PREDICTION OF AS-COMPACTED FIELD STRENGTH BY LABORATORY SEMULATION

Three sources of soil compaction data were sought: published works, Indiana State Highway Commission construction files, and field and laboratory data generated by project personnel. The published and construction file data were categorized and statistical analysis of variance and regression techniques were used on suitable sets for evaluation. The expected trends in general were noted; however, due to the statistical characteristics of these data firm conclusions could not be made as to what are the sources of the exhibited variability and behavior of the compacted soil. Field data were obtained by sampling a local highway embankment. From bag samples taken at the fill, laboratory compaction tests were used to generate additional data. The field and laboratory data yielded an encouraging relationship between field and laboratory as-compacted compressive strength for the soil. Modeling water content appeared as the dominant factor in the strength prediction model. Additional investigation is continuing. A recommendation was made to develop a test embankment for future field investigation; this should allow isolation of the compaction variables which are most influential in producing the variability observed in the field data. /Author/
