3430 Plus RoadReader

The Troxler nuclear moisture density gauges are used by many contractors, engineers, and highway departments for compaction control of soil aggregate, concrete, and full depth asphalt. The gauges meet or exceed the ASTM standards D6938, D2950, and C1040. The operator selects the density measurement mode, backscatter, or direct transmission based on the material type and the thickness of the layer being measured.
