- Density measurement capability in backscatter or direct transmission mode
- Moisture measurement in backscatter mode to allow quick, non-destructive testing of soil, asphalt and concrete materials
- Direct readout of test results (wet density, dry density, moisture, % moisture, % voids, and % compaction)
- Multiple count time options (15 seconds, 1 minute, 4 minutes)
- User-friendly menus and keypads
- Options of 12”/2”, 12”/1” and 8”/2” depth measurement capability
The gauges meet or exceed the ASTM standards D6938, D2950, and C1040.
4640-B Surface Thin Layer Density Gauge
Recognizing the need for an improved method of measuring the density of thin layer asphalt overlays, Troxler developed the first true thin layer density gauge, the 4640-B Surface Thin Layer Density Gauge.
Designed to measure the density of thin asphalt and concrete layers from 2.5 to 10 cm (1 - 4 inches), the Troxler Model 4640-B Thin Layer Density Gauge accurately measures the overlay density without influence from underlying material. No nomographs or manual corrections are required in order to compute the true density of the overlay. With onsite results available in as little as one minute, the Model 4640-B can provide the user with test results when they are needed, not hours after compaction has been completed. |
Special Functions:
The Troxler Model 4640-B Thin Layer Density Gauge complies with ASTM D2950 and AASHTO T 355.
- Automatic standard count comparison and storage
- Data storage of 750 records for later viewing, printing, and/or downloading
- Determination of the count time for selected precision
- Field offsets of density and a special calibration function
- Calculator mode
- Diagnostics and self-test modes
- Simple data transfer to a portable device using the free Troxler App

RoadReader 3450 Thin Layer & Full Depth Density Gauge
The RoadReader 3450 Thin Layer & Full Depth Density Gauge is the most versatile moisture density gauge ever produced. It combines the measurement modes proven in thousands of Troxler 3400 series gauges with a patented method for true thin layer asphalt and concrete bridge deck overlay density measurement.
By combining thin layer and full depth measuring capabilities in one instrument, the RoadReader 3450 is our flagship gauge in the 3400 series. With its versatility, speed, and economy, the RoadReader Plus is designed to satisfy your compaction control needs at every stage of your project. The RoadReader is simple to use. An expanded keypad and easy-to-follow prompts provide access to all major gauge functions. It also provides both density and moisture measurements without time-consuming calculations, including wet density, dry density, moisture, percent moisture, percent compaction, percent voids, and percent air voids. |
Additional Features:
Like all 3400 series gauges, the Model 3450 meets ASTM Standards D6938, D2950, C1040, and also AASHTO T 310 and T 355.
- A backlit screen provides exceptional viewing for low-light and nighttime testing.
- An adjustable beeper signals test completion over the roar of traffic or heavy equipment.
- The gauge stores up to 1,000 test readings under multiple projects for future use and/or download.
- The free Troxler App makes data transfer to a portable device simple.
