This paper presents the design features and measurement principles incorporated in this new gauge for asphalt density measurements. To measure asphalt density, this new gauge uses the backscatter mode, which is a non-destructive method. A nuclear densometer is a field instrument used in geotechnical engineering to determine the density of a compacted material. This gauge has a low-activity gamma-ray source and uses advanced detector technologies and algorithms. Nuclear gauges are also used for industrial, mining, and scientific purposes.

Recently, a low-activity nuclear gauge specifically designed for asphalt and soil density measurements was exempted from these nuclear regulatory requirements in the United States. A nuclear gauge (also called a nuclear density gauge, a soil moisture gauge, or a moisture density gauge) is a tool used for civil engineering projects and construction that measures soil density or soil water content. If you would like to book your Gauges in for servicing and calibration please call our office. The company is originally known for its nuclear moisture density gauges, but it also provides non-nuclear electromagnetic density devices as well as. These regulatory requirements have become a burden to some users. The densities of the Primary Calibration Standard Blocks are traceable to master standards of the National Institute of Standards and Technology (NIST), Gaithersburg, MD, USA. These gauges use radioactive sources and thus require licensing for ownership and use, gauge operator training, personal dosimetry, and special gauge storage. Troxler Non Nuclear Density Gauge A density gauge being used to ensure proper for the foundation of a school construction project. Gauge measurements are used to establish roller patterns, detect changes in the mix and process adjustments, and control density.
