Nuclear Moisture/Density Gauges
The Troxler Models 3430 and 3440 RoadReader™ nuclear moisture/density gauges measure the density and moisture of soil, aggregate, concrete and asphalt materials in the field for quality control purposes. These gauges offer two test modes: the direct transmission mode allows the source to be lowered below the surface in order to test a larger area of material and improve gauge precision. In backscatter mode, the source is positioned near the surface of the test material and the top four inches of material are penetrated by gamma rays. Moisture content of the material is also tested in a manner similar to the backscatter mode.
The Model 3440 provides advanced software, an automatic depth indicator and many special functions and features in order to achieve the highest level of operator convenience.
The Troxler RoadReader Plus, Model 3450, offers the unprecedented combination of surface moisture and density measurements with thin layer density determination in a single nuclear gauge. In addition, the 3450 provides a host of technical improvements and innovations, ensuring easier operation, greater reliability, and improved performance. To the testing laboratory that works mostly on soils with only occasional asphalt work, the RoadReader Plus offers a significant opportunity for expanded measurements. For municipalities or counties verifying overlays, trench fills, and reworks, the 3450 is a workhorse that addresses the full range of operational requirements. And for the DOT or large operator with a full range of needs, the 3450 offers tremendous flexibility in a single, easy to use gauge.
The Troxler Thin Layer Density Gauge, Model 4640, features patented technology to measure the density of thin asphalt and concrete layers from 2.5 to 10 cm (1 to 4 inches) without influence from underlying material. This model and the Model 3450 are the only nuclear gauges on the market capable of this method of density testing. This gauge is a must-have for paving contractors and others who have the need to monitor asphalt compaction regularly.
