Evaluation of non-nuclear density gauges
Webthose based on density gauges (nuclear density gauges [NDGs] and non-nuclear density gauges [NNDGs]). It is generally agreed that measuring core density in accordance with AASHTO T 166 (American Association of State Highway and Transportation Officials [AASHTO], 2007) or a similar procedure is the most accurate … WebThe study used comparative tests between the EGauge and the standard nuclear gauge on grading projects. Samples were ollectc ed to compare wet density, dry density, and moisture content using the different gauges. A recommendation was made to allow the use of the non-regulated nuclear gauge for wet density only and Materials IM 204, Appendix A

WebNov 25, 2024 · With the rapid development of power electronic techniques and the increasing cost of permanent magnets (PMs) materials, switched reluctance motors (SRMs) have recently gained more attention. However, traditional SRMs have a relatively low torque density. For the sake of increasing the motor torque density, this paper proposes a … WebFor the past several decades, density of freshly laid hot mix asphalt (HMA) mats has been measured by contractors, consultants or governmental agencies using nuclear density gauges. However, use of these devices requires the user to maintain an inordinate amount of records on the use of the equipment. These requirements include calibration and …
WebThe precision of all gauges in the lab was good, with standard deviations below 0.5 pcf with the non-nuclear gauges and less than 1.0 pcf with the nuclear gauge. Field-testing showed the PQI was a suitable alternative to the nuclear gauge for density profiling and joint density testing. WebLast decade observed a revolution in asphalt density measurement technique with the evolution of non-nuclear density gauges. This research work is carried out with the objective to determine the efficiency and accuracy of a newly developed non-nuclear density gauge i.e. PQI-380 for field conditions as it needs its thorough evaluation prior …
