The pavement testing equipment uses laser-based sensors to measure the deflection of pavement. According to the customer's individual requirements, we can mount sensors from 1 to 17pcs on different parts of the testing equipment in order to obtain accurate and varying results.

• 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.
• TBTGPR-10 is a portable high-performance GPR controller compatible with TBTGPR full series antennas. This device is versatile with wide application range, meanwhile automatically recognize antenna type and configure radar parameters. The Windows-system-based acquisition system is stable and reliable which saves both original data and in-field data. The controller accepts most external installed GPS and be able to add the geographic coordinate information to radar data. The digital signal is transmitted between controller and antenna with high anti-interference ability and good signal-to-noise performance.

• 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.
• TBTGPR-20 GPR is designed to portable with a cart so as to suitable for tube detecting. This ground penetrating radar is equipped with 200MHZ and 600MHZ antenna, to make the detecting more accurate.

This road surface profilometer consists of hardware(modular components) and software, which is widely used for inspecting the indices and characteristics of highway, pavement, airport runways, etc.
The device adopts laser sensor, accelerometer and DMI, which allows the testing for IRI (International Roughness Index), MPD (Mean Profile Depth), SMTD (Sensor Measured Texture Depth), etc.. In order to achieve different functions, the sensors can be configured from single to 17pcs according to customer’s requirement. The road surface profiling device is ideally suitable for both highway and airport.

• Modular system enables easy maintenance;
•  Real-time data collection for IRI, SMTD, speed, etc.
•  Testing at traffic speed enables faster measuring and saving time;
•  Real time graph display;
•  Adopts imported sensor from Republic of Belarus;
•  Equipped with imported accelerometer from USA Lance;
•  Conforms to ASTM E950 Class 1 profiling;

Pavement cracks, pits and other diseases that cause road surface technical conditions or road surface performance degradation are generally called as road surface damage. The severity of road damage seriously affects the speed of the vehicle and road.
This laser crack measurement system is 2D version, which adopts line-scan camera and the infrared laser to continuously collect the data of the asphalt pavement and cement concrete pavement. Based on the collected images of the pavement to identify the asphalt pavement disease (11 types of disease such as crack, block crack, etc.)
The laser system adopts the high resolution line-scan camera to seamlessly scan the lanes at longitudinal 1mm distance, each 2048mm forms a road image. Infrared laser-assisted illumination is used to achieve normal detection of road in all weather conditions and special environments (such as tunnels, culverts, cloudy days, nights, etc.) to obtain real road images.

• Full lane coverage, complete data collecting
  The laser system adopts the special structure design of single camera/laser. The designed road surface detection width can reach 3.5m or above, realizing the collection of full-width road surface data.
•  Available exposure and gain adjustment selection
  The system supports camera exposure and gain adjustment. During the detecting process, a suitable solution can be quickly selected to improve the efficiency of manual adjustment.
•  High image quality
  The system adopts a lens filter, which eliminates the influence of natural light and vehicle body shadow on image quality, which provides high image quality.

This high-precision walking profilometer is designed with an imported angular sensor & tablet. The pavement longitudinal profile can be measured during operator push-walking at normal speeds up to 3km/hr, then outputs such as IRI and SMTD(MPD) can be produced through calculation of mathematical models.
The walking profiometer can be widely used for inspecting quality of pavements, footpaths, tunnels, airport runways and building slabs, or being reference tool for calibrating & assessing for vehicle type high speed profilers.

Standards: JTGE 60-2008, JTG F80-2017, ASTM E2133.

Features
Portable in small size, simple operation.
Detecting system is connected to tablet by Wi-Fi.
Real-time results of IRI and MPD index & curve are displayed on tablet screen, which can be printed on site immediately.
Data acquisition & processing is performed by tablet.
Comparing with vehicle-mounted laser profiler, this walking-profiler detecting speed is slower, but the detection accuracy is higher.
