falling weight deflectometer
Asphalt Binder Tester

FEATURED PRODUCTS

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. 
This retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking.
The Retroreflectometer TBTTSR-1 is a portable, rechargeable battery-powered precision measuring instrument for the determination of night visibility (coefficient of retroreflection RA and R’) of traffic signs and safety garments.
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.
This machine consists of hardware(modular components) and software; The system adopts laser sensor, accelerometer and DMI which allows the testing for IRI, RN, RQI, SMTD etc., quantity of sensors can be from single upto 17pcs according to customer’s requirement to achieve different function; Ideal for both highway and airport; Our standard configure is 13pcs sensors;
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.

HOT PROJECT

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.

NEWS & EVENTS
The application of falling weight deflectometer
07-10
Since the evaluation indicators and standards specified in the current specification are based on the beckman beam test, the data measured by the falling weight deflectometer must be converted into beckman beam data through comparison test before strength evaluation can be carried out. However, the transformation relationship obtained by this simple regression analysis lost a lot of information of the measured data (especially dynamic information), and did not give play to the advantage of the measured sinker data form to evaluate the bearing capacity of the pavement structure.
The analysis of falling weight deflectormeter
07-06
With the development of road traffic infrastructure construction, more and more attention has been paid to the quality of road construction. Falling Weight Deflectometer has also become an important tool that is increasingly being valued by civil engineers. The falling weight deflectometer is one of the most advanced non-destructive testing equipment for pavement strength in the world. The working principle is as follows: the falling weight deflectometer measures the dynamic deflection of the road surface and inversely calculates the rebound modulus of the road surface. It has become a hot topic in the highway industry around the world.
Should you buy a retroreflectometer?
07-02
Many people know that retroreflectors can make a great contribution to ensuring road safety, but because retro reflector s are not really cheap, many people will hesitate: Should I invest in retroreflectors? Is this a cost-effective business?
Principle of retroreflector
06-30
If you are new to the car driver who is just starting to consider buying a car, it is highly recommended that you add the retroreflectometer to the purchase list. What is a retro reflector? Why is it important for road safety? How does the retroreflector work?
