The rolling thin-film oven test (RTFOT) method determines the resistance to hardening of asphaltic materials, bitumen or bituminous binders under the combined effects of heat and air.

Collect high-density, georeferenced GPR data across wide areas and view the subsurface in 3D as you scan. Choose the GX2 array for SUE and utility mapping, or the GX1 array for structural, bridge and pavement investigations.
Best suited to:
Best suited to:
Recommended array: GX2
Recommended array: GX1
Cover more ground
Collect multiple parallel profiles in one pass instead of uilding a grid line by line.
See results during acquisition
View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.
Produce repeatable mapped data
Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.
Use one platform for two very different applications
Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.
The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.
1. Plan the survey
Load satellite imagery, CAD information, project coordinates or survey control.
2. Collect dense multichannel data
Survey an approximately 0.82 m-wide swath with 11 channels in each pass.
3. Review data live
Examine radargrams, georeferenced time slices and marked features while still on site.
4. Interpret and digitise
Add points, linework, tags, photographs and field observations.
5. Process and deliver
Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.

UTB-0340A-T
UTB-0340A-T Bitumen Oven uses the rolling thin-film oven test (RTFOT) method to determine the resistance to hardening of semisolid asphaltic materials/ bitumen or bituminous binders under the combined effects of heat and air.
The Internal chamber of the UTB-0340A-T Bitumen Oven is insulated with fiberglass or similar, is made out of stainless steel, and has a door with a a symmetrically located window.
The oven has a programmable temperature controller which has a digital display system and works in PID mode. The oven uses a temperature sensor instead of the ASTM 13C thermometer. The digital unit on the oven displays the temperature and the temperature can be controlled by a mechanic switch on the oven. Conforming to the CE Directives.
Air Compressor and Air-Drying Unit (UTGE-3572) should be ordered separately. Maximum pressure should not exceed 2 bar when an air compressor is used.
The Bitumen Oven for RTFOT is supplied complete with;
UTB-0345-T
UTB-0345-T Bitumen Oven can be used to measure two different things, and uses two different methods to do so. Firstly, it is used to measure the loss in mass of oil and asphaltic/bituminous compounds by using the loss on heating test method. Secondly, it is used to measure the effect of heat and air on semi-solid asphaltic/bituminous materials with the thin film oven test (TFOT) method.
The internal chamber of the UTB-0345-T Thin Film Bitumen Oven is made of stainless steel and the door has a panel window.
The oven has a working temperature ambient to 200ºC , a digital PID controller and a circulation fan.
Rotating shelf and sample cups should be ordered separately according to the test type.

The GX1 transforms the GS9000 into a high-resolution structural assessment system for concrete slabs, bridge decks and pavements. Its dense, dual-polarisation array captures detailed 3D data across wide areas, supporting reinforcement and cover mapping, moisture and deterioration assessment, and analysis of asphalt and pavement layers. Live visualisation helps confirm survey coverage on site, while post-processing tools produce clear, report-ready condition maps.
1. Define the inspection area
Import the structure, bridge, pavement or survey background.
2. Collect closely spaced profiles
Capture 35 longitudinal and 15 cross-polarised channels with dense spacing.
3. Review coverage in the field
Use live radargrams and time slices to confirm that the required area has been captured.
4. Process the dataset
Apply velocity, gain, background removal, migration, filtering and topographic correction as appropriate.
5. Generate diagnostic maps
Create depth slices, reinforcement maps, layer information or application-specific condition maps.
6. Integrate with the engineering assessment
Export figures, mapped anomalies and raw data for inclusion in the engineer’s final interpretation and report.
