|---|---|
TBTHWD-NJ-M is with heavy loading capacity compare with TBTFWD, this machine is able to loading greater stress so as to simulate the loading of aircraft landing which make it’s mainly used for airport; This machine is also one of the most advanced non-destructive structure testing equipment for road surface strength, to measure dynamic deflection of road surface and calculate the rebound modulus of road surface.
TBTHWD, 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.

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 temperature 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. It can adopt third party analysis software with output data format of CSV or DDX.
