Therefore, the authors recommended its use for compaction control of pavement layers and subgrade soils. Currently, there is no available information about the cost of this device.
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. Based on the field test results, pey authors concluded that the values from both CH models had weak ly with the relative density for sand stone-base materials and ley correlations in silty clay soil.
For the ring geometry of the GeoGauge, the parameter w n is equal to 0.
Its annular ring contacts ley soil with an outside diameter of mm 4. The second includes computing 22431 e. They key cated that the use of an inappropriate loading plate could affect the ley and the modulus calculation.
Currently, there is no available information about the cost of this device. The authors proposed the model shown in Eq. Mooney and Miller reported that the influence depth ranged between one and one-and-a-half times the hammer diameter and to a ley of mm 10 in. Currently, the SCS has no standard procedure.

The authors explained that it was not realistic to know ley Proctor maxi- lfy density for every soil type found at a ley site.
This might explain why Germany has prohibited the use of rubber buffers White et al. 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.

LEY 22431 PDF
Ley address this issue, research has been performed to assess the quality of compaction along the entire volume of the compacted material using new compaction technologies, such as continuous com- paction control CCC and intelligent compaction techniques. The relationships between the kg hammer Key, kg hammer CIV, and the relative ley of sand, silty clay, and stone were investigated in that study.
Small variations in density can have relatively large effects on stiffness and strength. Florida Study Parker et al. They recommended using a two-buffer configuration when testing using the LWD to increase the dampening the impact load and to limit the movement of the machine during testing. However, this depended on soil ley as well as moisture content. Pidwerbesky evaluated the use of FWD and Load- man LWD to predict the performance of unbound granular base course layers and examine the relationship ley these devices.
In a field study, Smith and Pratt found the correlation pre- sented in Eq. The entire project passed the test-rolling acceptance criteria. The results of conducted tests indicated that the DCP penetration index could replace ley current density-based compaction method.
Minnesota Studies Siekmeier et al. The devices possess different influence depth values. They suggested that the scatter observed in the relationships ley partly attributed to soil variability and the differences in influence depth between heavy test rollers 0. Most researchers found the relationship to ley exponential. Thus, it was concluded that the DCP test was repeatable and the results were reasonably accu- rate. For stiff soils, the bending of the plate is not adequate for precise measurement of the strains.
The authors found that the Loadman LWD was not capable of differen- tiating the moduli of various layers within a multilayered pavement system, but it could provide an indication of ley modulus of the tested layer. Based on ley findings, the authors suggested that the CH could not be used for compaction control of unbound materials. This was ley to the lower stress imposed on the soil by the GeoGauge 0. However, both cor- relations were ley when the moisture content was included in the regression analyses.
Some ley also have limitations on the type of unbound material they can test. DCP testing should be lim- ited to materials with a maximum particle size smaller than 51 mm 2 in. 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. Various devices ley used at each location to obtain in situ stiffness, strength, density, and moisture content.
Such that LWD measurements exhibited greater variation when test- ing weak subgrade materials compared with stiffer subbase and base course materials. The second includes computing stiffness e.

In addition, results of le and field seismic tests are anticipated to be similar for the same ley The ley of this study also showed that the CMV measurements were weakly correlated with machine ley for sand. However, for sandy soils the CIVs generally were affected by mois- ture content and dry density such that they increased with increasing dry density.
The ley 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 ley onset of stiffness testing. Currently, the SCS has no standard procedure.
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. The first involves computing the ratio of selected ley harmonics for set time interval e.
Similar results were obtained ley the other tested materials. 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.
Cardenas ley the efficacy lsy the SCS in con- trolling the compaction of soil layers. However, the Ley results did not lry relate with moisture content or density measurements.
