Falling weight deflectometer
Asphalt Binder Tester


Nanjing T-Bota Scietech Instruments & Equipment Co., Ltd. is a professional supplier in China, specializing in pavement equipment. Our main products including falling weight deflectometer, asphalt binder tester, kinematic viscometer, retroreflectometer, road surface profiler, etc. 
Falling Weight Deflectometer (FWD) is one of the most advanced non-destructive testing equipment of road surface strength in the world. It has become a hot topic in the field of road in the world to measure dynamic deflection of road surface and calculate the rebound modulus of road surface.
Pavement roughness, as the main factor of dynamic loads which from vehicle movement, can expedite deterioration of pavement as well as wear and tear of vehicles. By using RSP, the pavement roughness can be determined as IRI. TBTPQL-B is specialized to test IRI;
Determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids
It is designed for obtain high quality core drilling samples with additional functions especially for asphalt mixture specimen request. The instrument is small in size, easy to operate.
This device is for checking anti-skid performance of roads ad airport pavement, can be used both in the lab ad in-situ. Accords to BS, EN standard;
Axle Scale is a weighing instrument for measuring the weight of eachwheel axle of a car, in order to protect the pavement quality away from over weight damage; This model adopts touch screen with high quality, very popular exported to US and other countries.
TBTRMR-1J Road Marking Retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking. This instrument is to simulate the brightness of road marking that can be seen by the driver under the illumination of motor vehicles at night, and the measured parameter is the coefficient of retrorefection brightness at night in daytime, namely, RL & QD value.


Crossing mountains and seas, sets of TBT's advanced testing equipment arrives in the university laboratories in Hong Kong, Australia and Middle East,
serving the university's civil engineering laboratories and materials research institutions.
