Abstract: Soil water content and dry density are two important properties for compaction quality control. This paper presents a new method for determining soil water content and dry density using a single time domain reflectometry ...

Abstract: The waveforms from time domain reflectometry (TDR) tests on soil depend on the temperature of the soil being tested. This study provides a discussion of, and the basis for, temperature corrections for the parameters measured ...

Abstract: This paper provides a new methodology for determining soil water content and density under different compaction energies. A new calibration equation was introduced making use of the voltage drop associated with the first ...

Abstract: The civil engineering capstone senior design course at Purdue University involves all seniors in their last semester before graduation and is titled “Civil Engineering Design Project.” The course catalog describes it as ...

Abstract: Lime kiln dust (LKD) is used for modifying pavement subgrades to expedite construction on wet clayey soils. This paper describes the short-term development (typically, over the first

Abstract: Ottawa sand specimens premixed with 0, 3, and 5% bentonite by dry mass of sand were tested under undrained static and cyclic loading to investigate the effects of bentonite on the static and cyclic shear strength of the ...

Abstract: At sites in earthquake-prone areas, a reliable expression of the nonlinear dynamic stress-strain behavior of soil for the different depths of interest is needed for earthquake-response analyses. Most currently used geophysical ...
