Thermal conductivity of compacted silts and field evaluation of the Briaud Compaction Device and Light Falling Weight Deflectometer


"The specification and monitoring for quality control/quality assurance of compacted subgrades and base layers is a significant concern to engineers. Elastic moduli, though monitored less frequently by most DOTs than compaction, may provide a better indication of the quality of compacted base materials and pavements in road construction applications. The ability to gauge the condition of these materials during the construction process can improve the quality of the finished product. In this investigation, the thermal conductivity of compacted low plastic silt was studied under varying moisture contents and densities. A KD2 Pro thermal properties analyzer was used to measure the thermal conductivity of the compacted soil specimen and compared to water content, bulk density, and elastic moduli. Correlations between the thermal conductivity and other material properties were studied. A Light Falling Weight Deflectometer (LFWD) and Briaud compaction Device )BCD) were utilized to determine the elastic moduli of several materials"--Abstract, page iv.
