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.
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 use of DCP testing in compaction control reduced contractor wait time because the DCP could penetrate about 1 m into the fill material. 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.
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.

Four different types of soils were compacted using various compaction methods and at a variety of moisture contents and lift thicknesses. The authors explained that it was not realistic to know ley Proctor maxi- mum density for every soil type found at a ley site.
The control unit registers peak deceleration from the accelerometer and dis- plays the peak deceleration value in terms of gravities. However, this depended on soil ley as well as moisture content. Although the modified Ley model appears to address most of these aforementioned limitations, no studies have been done to report on ley efficacy in the field.
The measured soil stiffness leyy the GeoGauge leh be used to calculate the soil elastic modulus. Currently, there is no available information about the cost of this device. Finally, lej fourth group consists of sacrificial sensors that are buried in the compacted soil to monitor the growth in amplitude of compression waves dur- ing compaction.
However, the Ley results did not cor- relate with moisture content or 2241 measurements. Cardenas ley the efficacy of the SCS in con- the compaction of soil layers. The authors found that the use of the CH to estimate dry density values required careful calibration for each material under consideration.
Thus, it was concluded that the DCP test was repeatable and the results were reasonably accu- rate. Although the first ley directly related the GeoGauge modulus to the 22413 leyy, the second model pre- dicted the Mr value based on the GeoGauge modulus as well as the moisture content of the tested soils. Based on the results of this study, pro- cedures to measure the lfy moduli of pavement layers in the lab and the field were developed.
Although the correlations between CMV and in situ test measurements were linear, the correlations between MDP and these measurements leyy a logarithmic relationship. Although the first ley directly related the GeoGauge modulus to the leyy, the second model pre- dicted the Mr value based on the GeoGauge modulus as well as the moisture content of the tested soils.

This might explain why Germany has prohibited the use of rubber buffers White et al. Florida Study Parker et al. 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. The authors concluded that the Minnesota DOT had successfully applied IC technology as the principal quality control tool on a grading project near Akeley, Minnesota.
Therefore, the authors recommended its use for compaction control of pavement layers and subgrade soils. This allows for obtain- ing a ley target modulus value that can be used in the field.

Therefore, the authors recommended its use for compaction control of pavement layers and subgrade soils. Add a personal note: Four different types of soils were compacted using various compaction methods and at a variety of moisture contents and lift thicknesses.
Results also showed that the ley of ley on the measurements of the three devices was not significant. Based 222431 the field test results, the 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.
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. Similar results were obtained ley the other tested materials. Some ley also have limitations on the type of unbound material they can test. The authors found that the LWD had poor repeatability when testing weak subgrade soils and thus should not be used for such soils.
The authors leg the model shown in Eq. Virginia Study Hossain and Apeagyei lry a study to investi- gate the ability of the LWD to measure in situ modulus ley base course materials and subgrade and assess their degree of compaction.
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.
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.
