measuring devices which monitor the change of soil response due to the application of impact or vibrating force on the soil. All the devices, however, provided a measure of soil densification and they could be used satisfactorily to replace the NDG when they are properly correlated to soil relative compaction.
· Fracturing or cutting subsurface compacted soil has, in some cases, resulted in remarkable yield increases. Many Pennsylvania producers suspect they have a subsurface compaction problem, but have no handle on how to measure it. A diagnostic tool to measure the extent and depth of subsurface compaction is a penetrometer, or soil compaction tester.
For soil compaction testing moulds and rammers are used to determine the connection between the density and moisture content of compacted soil. The local standards that define compaction testing in Australia are AS 1289.5.1.1 and 1289.5.1.2. PCTE's range of test hardware include standard and modified compaction moulds and handheld manual .
The Briaud compaction device (BCD) is a simple, small-strain, nondestructive testing apparatus that can be used to evaluate the modulus of compacted soils. The use of the BCD as a field testing device for compacted soil quality control may be more beneficial than the current practice of measuring in …
· The soil compaction process (Harris, 1971) and other means of measurement (Freitag, 1971) have also been described Most penetrometers can be adapted to many uses The Proctor penetrometer was, for example, successfully used to measure soil compaction or hardness caused by the long term effects of continuous and fixed seasonal grazing treatments .
required for compaction control. Of the devices tested, two devices based on the measurement of electrical soil properties showed the most promise. However, improvements are required before these devices can be used in practice. 17. Key Words Compaction, Density, Water Content, Nuclear Gauge 18. Distribution Statement No restrictions.
Compaction is achieved by applying a pre s s u re on the surface or by vibrating the soil mass. Di f f e re n t compaction methods are needed for different types of soils and the amount of compaction re q u i r ed for dif-f e r ent soils must be established using standard testing p ro c e d u re s. Measuring compaction
The Briaud compaction device (BCD) is a simple, small-strain, nondestructive testing apparatus that can be used to evaluate the modulus of compacted soils. The use of the BCD as a field testing device for compacted soil quality control may be more beneficial than the current practice of measuring in …
A laboratory evaluation of one such commercially available device, known as the GeoGauge, is described. The GeoGauge measures soil stiffness, arguably a more viable engineering parameter than moisture-density measurement. The GeoGauge was found to measure soil stiffness as advertised.
Additionally, many of the devices do not provide a measure of water content, and thus would require another device to measure water content when water content is required for compaction control. Of the devices tested, two devices based on the measurement of electrical soil …
vibratory and static modes. Regardless of the technology, by making the compaction machine a measuring device and insuring compaction requirements are met the first time, the compaction process can be better controlled to improve quality, reduce rework, maximize productivity, and minimize costs (White et al. 2006).

ent soil resistance ranges (Fritton, 1990; Vyn and Raim-Abstract bault, 1993). The dynamic penetrometer design de-Recognition of the importance of soil compaction is increasing, scribed addresses these concerns. but instrument cost, measurement repeatability, and data interpreta-tion limit its measurement on agricultural and rangelands.
· Poor compaction decreases pavement quality Failures such as rutting, raveling and moisture damage are commonly attributed to poor compaction, and as a result, this is one of the main metrics measured when assessing quality. Low density pavements can impact project payment incentives and in the longer term could cause accelerated failures where poorly compacted pavements may …
Soil compaction equipment for tests such as the Proctor, both standard (ASTM D698 or AASHTO T99) and modified (ASTM D1557 and AASHTO T180) variants. Proctor testing was developed in the early 1930s and has been used extensively to determine the relationship of moisture and density in …
I have used a similar compaction measuring device in an evaluation of pipeline damage to a high-clay content black soil. Interestingly, and contrary to the claim, the soil directly over the pipeline was much less compacted than the soil on either side of the pipeline trench which was highly compacted well beyond the traffic area used for laying the pipe.
The results of the research program "Evaluation of Soil Compaction Measuring Devices" have shown the applicability, and limitations, of the tested compaction measuring devices in restoring utility trenches, keyholes and bellholes. The final report (available at …
The soil bulk density (ρ) indicating soil compaction was measured on-line by means of a developed compaction sensor system that comprised several sensors for on-line measurement of the draught (D .
Soil compaction is related to dynamic properties that change with time due to various crop operations and environmental factors. Measuring soil compaction is usually a tedious, time consuming and expensive task. One approach frequently taken to investigate the variability in physical properties of the soil is to measure soil strength indices .
Compaction measurement devices and data returned by each device (Ernest S. Berney et . these properties give a better evaluation of the functionality of . . nuclear devices for soil compaction .
