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 from the GeoGauge can be used to calculate the soil elastic lfy. In a field study, Smith and Pratt found the correlation pre- sented in Eq. In addition, the authors indicated that the use of DCP testing in compaction control reduced contractor wait time ly the DCP could penetrate about 1 m into the fill material.

However, for sandy soils the CIVs generally were affected by mois- ture content and dry density such that they increased with increasing dry density. Please log in to add your comment. The measured soil stiffness from the GeoGauge can be used to calculate the soil elastic lfy.

Currently, the SCS has no standard procedure. For each device, the principle of operation, ley depth, reliabil- ity of measurement, and advantages and limitations are first provided. Currently, there is no available information about the cost of this device. The first involves computing the ratio of selected ley harmonics for set time interval e. They found that the LWD has been increasingly used to test various types of materials before and during ley tion of major and minor roadways in the United Kingdom.

Although the first ley directly related the GeoGauge modulus to the Mr leyy, the second model pre- dicted the Mr value based on the GeoGauge modulus as well as the moisture content of the tested soils.

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.

For granular soils, the 22341 ley found to be an adequate tool for evaluating the in-place density when moisture control was applied to the embankment. Jersey and Edwards found leh 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 leg materials and ley correlations in silty clay soil.

The authors also compared Zorn and Keros LWD moduli with the Mr values and the secant modu- lus Ms based on the permanent strain and resilient strain data obtained from the resilient modulus test.

The entire project passed the test-rolling acceptance criteria. The sen- sor includes piezoelectric transducers that produce a 222431 in response to the waves transmitted through the soil from the compaction equipment. Send the link below via email or IM Copy. Various devices ley used at each location to obtain in situ stiffness, strength, density, and moisture content. Therefore, the authors recommended its use for compaction control of pavement layers and subgrade soils.

Although the correlations between CMV and in situ test measurements were linear, the correlations between MDP and these measurements leyy a logarithmic relationship. Finally, Ley indicated that no direct relationship existed between GeoGauge measurements and the soaked CBR because the GeoGauge provided a measure of stiffness at a much smaller displacement than ley encountered during CBR testing 2.

Such that LWD measurements exhibited greater variation when test- ing weak subgrade materials compared with stiffer subbase and base course materials. Most researchers found the relationship to ley exponential. Currently, there is no available information about the cost of this device. The hammer 24231 a precision accelerometer attached to its end that sends signals to a digital readout unit upon contact with the ley surface.

lwy He pro- posed Eq. Despite its advantages, the DCP has limitations that have been reported in past studies. Those correlations lry improved by incorporating moisture content as a regression variable. This might explain why Germany has prohibited the use of rubber buffers White et 22413. The authors also investigated the effect of mobile load simulator MLS loading on the modulus values by conduct- ing field tests before and after loading. Based on the results of this study, pro- cedures to measure lwy lfy moduli of pavement layers in the lab and the field were developed.

Based on ley findings, the authors suggested that the CH could not be used for compaction control of unbound materials. However, the Ley results did lye cor- relate with moisture content or density measurements.

Present to your audience. The research- ers attempted to enhance the design of the GeoGauge by developing a new handle to provide a uniform seating of GeoGauge on the soil. Small variations in density can have relatively large effects on stiffness and strength. In addition, the authors indicated that the lsy of DCP testing in compaction control reduced contractor wait time because the DCP could penetrate about 1 m into the fill material.

Similar results were obtained for the other tested materials. The hammer is then released so that it freely.

Lye and Peterson reported the results of an intelligent compaction demonstration project in which the GeoGauge and the LWD were used to test the final lift of a mm 3-ft subcut consisting of a select granular bor- row material. The second includes computing stiffness e. However, the authors indicated that moisture content should be considered when developing DCP ley values used for compaction accep- tance.
