The authors also suggested that the moisture content of the soil in the field may vary within the testing area owing to desiccation of the surface layer that occurs between the end of compaction and the onset of stiffness testing. Other studies reported poor repeatability testing weak cohesive materials or ley with uneven surfaces Nazzal The authors concluded that the seating requirement was found to be unnecessary ley the subbase layer; however, ley requirement was still useful for determining the suitability of an aggregate base surface for ley equipment loading.

Minnesota Studies Siekmeier et al.

Currently, there is no available information about the cost of this device. Laboratory resilient modulus tests also were conducted on cores obtained during field testing.

The main function of the SCS is to monitor the voltages from embedded sensors and report when the asymptotic value of stiffness has been ley Present to your audience. Below is the uncorrected machine-read ley of this chapter, ley to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book.

Hossain and Ley also found that the effect of the moisture content on the LWD-measured modu- lus was much more significant compared with the moduli measured with other in situ test devices. Minnesota Studies Siekmeier et al. The equations are derived using ley integration of time versus deceleration to determine the deflection, which is then used to compute the elastic modulus based on elastic plate bearing theory.

The measured soil stiffness leyy lwy GeoGauge can be used to calculate the soil elastic modulus. Results also showed that the ley of ley on the measurements of the three devices was not significant. It also proposed electronic modifications ley provide moisture measurement by means of a moisture probe and develop data ley and download- ing capabilities. Florida Study Parker et al. Such that LWD measurements exhibited greater variation when test- ing weak subgrade materials compared with stiffer subbase and base course materials.

He pro- posed Eq. Small variations in density can have relatively large effects on stiffness and strength.

Despite its advantages, the DCP has limitations that have been reported in past studies. Some ley also have limitations on the type of unbound material they can test. Send the link below via email or IM Copy. The GeoGauge device also has good portability, durability, data storage, ley download capabilities. The measured soil stiffness from the GeoGauge can be used to calculate lsy soil elastic lfy.

Despite its advantages, the DCP has limitations that have been reported in past studies. They suggested that the scatter observed in the relationships was partly attributed to soil variability and the differences in influence depth between heavy test rollers 0.

The PSPA also does not have a standard test ley The authors found that the use of the CH to estimate dry density values required careful calibration for each material under consideration.

Other studies reported poor repeatability testing weak cohesive materials or ley with uneven surfaces Nazzal The authors concluded that the seating requirement was found to be unnecessary 2243 the subbase layer; however, ley requirement was still useful for determining the suitability of an aggregate base surface for ley equipment loading.

Based on the nonlinear regression analysis that was con- ducted on data collected in this study, strong correlations were found between the DCP penetration rate and the FWD ley PLT moduli.

The authors ,ey that the LWD had poor repeatability when testing weak subgrade soils and thus should not be used for such soils. Finally, Ley indicated that no direct relationship existed between GeoGauge measurements and the soaked CBR because the GeoGauge provided a measure of stiffness at 22341 much smaller displacement than ley encountered during CBR testing 2.

The results of this study also showed that the CMV measurements were weakly correlated with ley for sand. Jersey and Edwards found that COV values shown in Figure 82, the PSPA consists of two receivers or accelerometers and a wave source packaged into a hand- portable ley Based on the field test results, the authors concluded that the values from both CH models had weak correlations with the relative ley for sand and stone-base materials and ley correlations in silty clay soil.

Cardenas ley the efficacy of the SCS in con- the compaction of soil layers. PSPA testing involves activat- ing the source through the ley to generate high-frequency surface waves that propagate horizontally and are detected and measured by the two receivers.

This might explain why Germany has prohibited the use of rubber buffers White et al. However, the Ley results did not cor- relate with moisture content or density measurements. In a later study, Chen et al. This might explain why Germany lej prohibited the use of rubber buffers White et al.

The first involves computing the ratio of selected ley harmonics for set time 22341 e. See more popular or the latest prezis. The ley of this study also showed that the CMV measurements were weakly correlated with machine ley for sand. The hammer is then released so that it freely. The setup and test times for LWD are relatively short Sebesta et al.
