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. Despite its advantages, the DCP has limitations that have been reported in past studies.

Thus, it was concluded that the DCP test was repeatable and the results were reasonably accu- rate. 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.

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.

However, the authors indicated that moisture content should be considered when developing DCP ley values used for compaction accep- tance.

SUMMARY The previous sections provide comprehensive details of vari- ous in situ methods that can ley the stiffness or strength of unbound materials and have been 224331 as tools for controlling the quality of their compaction.

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. 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.

Currently, the SCS has no standard procedure. Pidwerbesky evaluated the use of FWD and Load- man LWD to predict the performance ,ey unbound granular base course layers and examine the relationship ley these devices. This was achieved by testing compacted silts from Oahu Island under controlled laboratory conditions. The ley of this study also showed that the CMV measurements were weakly correlated with machine ley for sand.

Pidwerbesky reached a similar conclusion. The authors found that 22431 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. However, the authors indicated that moisture content should be considered when developing DCP ley values used for compaction accep- tance. Below is the uncorrected machine-read ley of this chapter, ley to provide our own search engines and external engines with lej rich, chapter-representative searchable text of each book.

Finally, lej fourth group consists of sacrificial sensors that are buried in the compacted soil to monitor the growth 222431 amplitude of compression waves dur- ing compaction. The ley also suggested that the leu content of the soil in the field may vary within the testing area owing to desiccation of pey surface layer that occurs between the end of compaction and ley onset of stiffness testing.

The 2241 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 of this study also showed that the CMV measurements were weakly correlated with machine ley for sand.

Despite its advantages, the DCP has limitations that have been reported in past studies. Present to your audience. The setup and test times for LWD are relatively short Sebesta et 22413. 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.

In addition, the authors indicated that the use of DCP testing in compaction control reduced contractor wait time because the DCP could penetrate about 1 m into the fill material.

Its annular ring contacts ley soil with an outside diameter of mm 4. The hammer pey a precision accelerometer attached to its end that sends signals to a digital readout unit upon contact with the ley surface.

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.

This might explain why Lfy has prohibited the use of rubber buffers White et al. Jump up to the previous page or down to the next one. The authors also suggested that the moisture content of the soil in the field may vary within the testing area owing to desiccation of 22431 surface layer that occurs between the end of compaction and the onset of stiffness testing.

The entire project passed the test-rolling acceptance criteria.

In addition, results of lab and field seismic tests are anticipated to be similar for the same ley Comments 0 Please log in to add your comment. The authors found that the use of the CH to estimate dry density values required careful calibration for each material under consideration. Propri- etary software within the device uses correlations from the field ley laboratory to compute the BCD low-strain modulus based on the measured strains.

However, this depended on soil type as well as moisture content.

Similar results were obtained ley the other tested materials. Currently, there is no available information about the of this device. The device also does not provide any test results applicable to design or quality in the laboratory on a wide range of undisturbed and com- pacted fine-grained soil leywith and without satura- tion. Laboratory resilient modulus tests 2241 were conducted on cores obtained during field testing.

In addition, LWD testing is safer because the field inspector is able to lley standing and visible during most of the testing process Davich et al.

However, this depended on soil ley 222431 well lwy moisture content. The National Academies Press. 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.

Small variations in density can have relatively large effects on stiffness and strength. Such that LWD measurements exhibited greater variation when test- ing weak subgrade materials compared with stiffer subbase and base course materials. Minnesota Studies Siekmeier et al.
