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. 
This is Friction Tester is an accurate and repeatable, self-contained continuous friction measuring equipment (CFME); It provides coefficients of friction (Mu) on airport runways.
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.
Determine softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and various asphalts. It can be widely used for asphalt manufacturing companies, highway and bridge construction companies, relative colleges and universities, and scientific research institutes.
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 to 17pcs according to customer’s requirement to achieve different function; Ideal for both highway and airport;
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.
