...Yaru Lv; Jiagui Liu; Dianjun Zuo The dynamic behavior of calcareous sand at high strain rates (HSRs), which is relevant to mining industry, aircraft wheel loading, and pile driving, is still not fully understood. To investigate the effects of the moisture content, 34 HSR tests and 26 low strain...

... by cutting a core from the soil mass. According to ASTM D6951-09 (2009) the soil density may be estimated if the soil type and moisture content are known from the dynamic cone penetrometer (DCP) penetration rate. The DCP test is a soil-penetration test that is used for the measurement of sub-grade strength...

...Gurdev Singh; Braja M. Das; M. K. Chong Interpretation and reliability of in situ tests, such as cone penetration, can be improved if in situ moisture content and density can be measured without affecting the speed of site investigation significantly. This paper describes the principle...

...Christopher L. Meehan; Jason S. Hertz In situ measurements of soil unit weight and moisture content play a critical role in conventional compaction quality assurance and quality control procedures. Recently, there have been a number of attempts to develop alternative electrically-based test devices...

.... However, the water flow analyses in the MEPDG are not well validated using field measurements of moisture content and matric suction with time. A research study was initiated to measure the variation in matric suction and moisture content in an expansive soil during seasonal fluctuations. Specifically...

... measurements such as, density, in-situ moisture content, stiffness measurements using a soil stiffness gage, surface deflection tests using the light falling weight deflectometer (LFWD) and falling weight deflectometer (FWD), and penetration tests using a dynamic cone penetrometer (DCP), were also done...

The relationship between energy and engineering properties of soils can provide a basis to correlate different geotechnical engineering behaviors that have customarily been individually studied. Consequently, a new...

Accordingly, at developed sites, the change in moisture content in soils underlying developed sites does not necesssarily follow a typical seasonal or cyclic pattern. Consequently, the main problem in this region is generally soil swell rather than shrinkage...

... is further simplified by introducing a model that only uses the moisture content variation to determine the amount of heave. Close agreement is observed between measured and model-predicted shale behavior. Application of this simplified model eliminates the difficulty of recovering an undisturbed specimen...
