This book was released on 2005. A Working Review of Available Non-nuclear Equipment for Determining In-place Density of Asphalt available in PDF, EPUB and Kindle. Current non-nuclear methods of measuring asphalt pavement density use electrical properties of asphalt. Two known instruments, the PaveTrackerTM and the PQI Model 300, estimate pavement density by inferring the relative proportion of air-filled voids in the asphalt from a measure of dielectric permittivity. Under this project, currently available and new methods of determining in-place asphalt density were investigated. The investigation included a laboratory study of the PaveTrackerTM's ability to accurately measure density under a variety of conditions, including coarse or fine aggregate in mix, presence of internal and/or surface moisture, sample area, and sample depth. Both the PaveTrackerTM and the PQI Model 300 were evaluated in the field by measuring density of measurement locations at each of 24 project sites and comparing to corresponding values measured by a nuclear gauge and laboratory tests. Recommendations for practice, including expected payoff results in using them, are given.

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.
