TBTFWD is one of the most advanced non-destructive structure testing equipment for road surface strength, as it’s a hot topic in the field of pavement test to measure dynamic deflection of road surface and calculate the rebound modulus of road surface.
TBTRMR-1J is used to determine the retroreflective properties by simulating the process in which vehicle headlamps illuminate the road/airport markings and then reflect light back to the driver.
TBTRMR-VM Mobile Retroreflectometer for Road Marking provides continuous and efficient assessment and full overview of the condition of the road markings at traffic speed without blocking traffic.
TBTPAV-II Bitumen PAV System consists of TBTPAV-I Pressure Aging Vessel(PAV) & TBTPAV-II Vacuum Degassing Oven(VDO). TBTPAV-I Pressure Aging Vessel(PAV) simulates the accelerated aging process of asphalt binders in service on road by high pressure and temperature. TBTPAV-II Vacuum Degassing Oven(VDO) removes air bubbles created during the in-service oxidative ageing of asphalt binder.
TBTBBR-1 Bending Beam Rheometer is designed according to AASHTO T313, ASTM D6648 and EN 14771 to perform flexural creep stiffness of asphalt binder at the low-temperature condition. Each TBTBBR-1 consists of load frame, built-in touch screen industrial computer, fluid bath, chiller, calibration kit, air compressor and power box.
TBT-2806GW is designed and made referring to ASTM D36 Standard Test Method for Softening of Bitumen (Ring-and-Ball Apparatus).
TBTLWD series Light Weight Deflectometer is a non-destructive(NDT) instruments, also called as dynamic deformation modulus tester (hand-held drop hammer deflection meter), it is used to determine the deflection capacity of the sub-grade under the dynamic load, thereby evaluating the bearing capacity and deformation of the sub-grade.
TBTGPR series ground penetrating radar is a versatile GPR system offering various detecting combination for application in highway, roads, tunnel construction, paving, buildings, bridges, water conservancy, municipalities or military.
TBTFWD is one of the most advanced non-destructive structure testing equipment for road surface strength, as it’s a hot topic in the field of pavement test to measure dynamic deflection of road surface and calculate the rebound modulus of road surface. TBTFWD is used 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.
