note = "A traditional quality control and quality assurance tool for asphalt pavement in-place density is a nuclear density gauge. There tend to be problems, however, in nuclear-based devices associated with storage, equipment handling, and licensing. A non-nuclear device that determines asphalt pavement layer density based on the principle of electrical impedance and associated materials' dielectric constants is the Pavement Quality Indicator (PQI), manufactured by TransTech Systems, Inc.",
