Evaluation of Soil Compaction Measuring Devices

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.

Diagnosing Soil Compaction Using a Penetrometer (Soil

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.

Field Evaluation of Compaction Monitoring Technology

Field Evaluation of Compaction Moni­ Soil compaction was then displayed in real time on a ruggidized computer monitor placed in the cab of the roller. In essence, this research used the compaction machine as a measuring device to help control the compaction process

Evaluation of Non-Nuclear Methods for Compaction Control

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.

Laboratory Evaluation of the Briaud Compaction Device

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

EVALUATION OF A MECHANICAL STIFFNESS GAUGE FOR

describes the evaluation of one such commercially available device known as the GeoGauge. The GeoGauge measures soil stiffness, arguably, a much more viable engineering parameter than the moisture-density relations currently used. The GeoGauge was found to measure soil stiffness as advertised. Results relating moisture, density,

MEASURING SOIL COMPACTION ON CONSTRUCTION

acterize soil compaction and to find a proper measurement method. Another difficulty is char-acterizing soil compaction in deeper soil layers. Randrup (1997) showed that clay soils on con-struction sites were compacted to depths of 0.8 in (32 in.). A bulk density measurement by the use of core sampling has been described by many (e.g.,

DEVELOPMENT AND VALIDATION OF SOIL MEASUREMENT DEVICES

Goals / Objectives To develop and evaluate soil pressure measurement devices and to determine maximum soil pressures generated by land mine excavation vehicles which will not trigger land mines. Project Methods A series of soil bin experiments will be conducted to evaluate and determine the effects of vehicle and soil parameters on soil pressures.

Field comparison of two prototype soil strength profile

Soil compaction caused by wheel traffic of large agricultural Evaluation of this instrument (Glancey et al., 1996) showed that force distri-bution over the tillage depth was linear at a shallow operating device so that it could measure soil mechanical impedance

Soil Compaction Measurer. Soil and Amendments HayTalk

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.

Evaluation of the dynamic cone penetrometer to detect

Jan 01, 2018· A hand-held “PANDA 2” DCPT device (90° cone angle, projected cone area 200 mm 2, ∅16 mm head, ∅14 mm shaft), capable of measuring cone resistances q d ≤ 30 MPa, was used to measure dynamic penetration resistance before and after the passage of an agricultural vehicle. The PANDA 2 can be used by a single operator, making it useful for large-scale field testing as shown in
