FWD(Falling Weight Deflectometer) is one of the most advanced non-destructive structure 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, ideal equipment for comprehensive testing. Use our FWD-NJ-M, to ensure road safety and ensure people's lives. We provide portable, light, HWD Heavy Falling Weight Deflectometer. 

TBT Road Surface Profilometer for Single IRI plus Single SMTD；For pavement testing with auto data acquired;
Other versions, IRI+ SMTD, IRI+MPD, IRI+MPD+RUT are avaiable, We also have LCMS(2D/3D), Road Asset system for your choice.

TBTACZ-5 Wheel tracker is designed to evaluate the anti-rutting ability of asphalt mixture at high temperature and help with the ratio design of asphalt mixture. It’s widely used in asphalt laboratory, it consists of a loaded wheel, which bears on a sample held on a moving table, you can find in this short video;

TBTRMR-1J Road Marking Retroreflectometer is to simulate the brightness of road marking that can be seen by the driver under the illumination of motor vehicles at daytime & night, namely, RL (night visibility), QD (day visibility) under dry conditions.

TBT retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking. TBTRMR-1 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, namely, RL value.
