The instrument is a new type of road surface testing instrument designed for high-precision flatness assessment. It is ideal for quality acceptance of under-construction and reconstruction road surfaces. The system operates efficiently under normal traffic conditions, provided there are no serious potholes, ruts, water accumulation, or snow.
With an accuracy reaching up to 0.01mm, the instrument generates reliable smoothness data for asphalt pavements. This information is transmitted at high speed to a computer via dedicated software, which processes the data to output calculation tables and raw waveform data.
The upper computer program runs on Windows operating systems, allowing for seamless collection, storage, printing, processing, and generation of detailed analysis reports.
The vehicle travels at constant speeds (20-80km/h) while laser sensors scan the road surface at high frequencies (10-50kHz) to obtain continuous elevation profiles.
The IMU monitors pitch, roll, and vertical displacement in real-time, eliminating body motion interference through advanced algorithms.
Software converts elevation data into International Roughness Index (IRI) indicators and can generate 3D pavement models or defect maps.
Suitable for large-area rapid detection with speeds significantly higher than manual or pushed equipment.
The combination of laser and IMU achieves sub-millimeter level measurement, meeting international ASTM E950 standards.
Supports real-time display of results, facilitating immediate on-site decision-making and quality control.
Data exports in common formats (CSV, XML) for integration with road maintenance systems (PMS).
