LHBP-5 Continuous Eight-Wheel Planeness Tester (Eight Wheels)
The LHB P-5 pavement profiler is a new type of pavement profiler. It was developed by incorporating user feedback on the LHB P series pavement profilers, retaining the advantages of the original instrument. In terms of electronic technology, it adopts the most advanced microprocessing and large-scale integrated circuit technology in China, improving the overall integration, reducing many unnecessary connector connections in the original instrument, thereby increasing the reliability of the system's operation, making the performance of the entire machine system more stable. Internally, it uses a single CPU structure, responsible for display, printing, calculation, communication, and data acquisition functions; it uses an interrupt method to sample data, so continuous measurements can be performed without interruption. Distance is calculated automatically; when 1000 data points are stored in memory, with a sampling interval of 0.1 meters, it can continuously measure 25 kilometers.

PS-I type asphalt pavement depth construction instrument
The principle is to spread dry sand of known volume and specified particle size into a circle of a certain area on the road surface. The ratio of the volume of sand to the average area of the covered surface is called the structural depth of the road surface. The unit is millimeters. It can reflect the macroscopic roughness of the road surface.

LHDZ-105 Laser Road Surface Smoothness and Rut Depth Detection System
This device can quickly, accurately, and in real-time detect and calculate indicators such as the International Roughness Index (IRI), structural depth (SMTD), rut depth (RD), bump (PB), wear index (PW1), riding quality index (RQI), observation score (RN), test speed, and driving distance for various levels of highway pavement. It can provide comprehensive and efficient data support for project completion acceptance, preventive maintenance, and pavement management systems (CPMS).
