This report describes research efforts to determine if commercially available non-nuclear density gauges can be used for TxDOT's density profile and joint density testing procedures. Researchers conducted testing with a Troxler 3450 nuclear gauge (operated in the thin-lift mode) and the Pavetracker (PT) and Pavement Quality Indicator (PQI) non-nuclear gauges. In a laboratory setting, research showed all the gauges could be affected by mix temperature, where gauge readings typically decreased with decreasing mix temperature. All gauges readings were also impacted by moisture, with the nuclear gauge least impacted. The 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.

Investigation of Electromagnetic Gauges for Determining In-place HMA Density available in PDF, EPUB and Kindle. Density is an important component of hot-mix asphalt (HMA) pavement quality and long-term performance. Insufficient density of an in-place HMA pavement is the most frequently cited construction-related performance problem. This study evaluated the use of electromagnetic gauges to nondestructively determine densities. Field and laboratory measurements were taken with two electromagnetic gauges-a PaveTracker and a Pavement Quality Indicator (PQ1). Test data were collected in the field during and after paving operations and also in laboratory on field mixes compacted in the lab. This study revealed that several mix-and project-specific factors affect electromagnetic gauge readings. Consequently, the implementation of these gauges will likely need to be done utilizing a test strip on a project- and mix-specific basis to appropriately identify an adjustment factor for the specific electromagnetic gauge being used for quality control and quality assurance (QC/QA) testing. The substantial reduction in testing time that results from employing electromagnetic gauges rather than coring makes it possible for more readings to be used in the QC/QA process with real-time information without increasing the testing costs.
