TBTFWD is one of the most advanced non-destructive structure testing equipment for road surface strength, as it’s a hot topic in the field of pavement test to measure dynamic deflection of road surface and calculate the rebound modulus of road surface.

TBTFWD is to apply a known amount of stress to the pavement and then record the deflections produced due to the impact. Ambient temperature and pavement surface temperature are automatically measured by the equipment while asphalt temperature is measured manually. With required interval of points, the geophones are placed on the geophone beam, to get the deflection value when force loaded, and on the data acquisition software you can find these values and see the deflection basin.

Features:

1. Easy to operate, fully-automatic;

2. “One-Key Operation”, the whole testing can be completed by one person with pressing just one key on laptop.

3. Fast measurement, 20~30s/point.

4. Four segmented plate which can fit the uneven pavement surface better;

5. Auto GPS location; auto surface/ambient temp. measuring

6. Storage Battery Charging: charging by electric generator on the tractor

7. Double Locking System: Hydraulic/ Mechanical

8. Emergency System: Lift the load plate when system breaks down.

9. Operation Options: Manual/ Automatic

10. Two camera: one for monitoring loading plate action; one for connecting with tractor;

11. Inertia Braking; Synchronized turn/break/back light and head warning light with the tractor

12. Been approved with AASHTO R32 calibration;

13. Adapting to third party analysis software(such as) with output data format of CSV or DDX;

14. Mounted on the vehicle, easy operating and future maintenance;
