The Hohhot bureau of science and technology recently announced that a project led by Inner Mongolia Road & Bridge Group has been selected for the national list of "14th Five-Year Plan" high-quality development demonstration projects in the transport sector.

The selected project – a high-frequency dynamic precision measurement and control system for 3D-printed roadbeds and pavements based on BeiDou and millimeter-level self-sensing positioning technology – highlights the company's strong technological capabilities in intelligent transportation infrastructure equipment.

It also serves as a model for how Hohhot's high-tech enterprises continue to break through technical bottlenecks and strengthen their core competitiveness.

A key strength of this achievement lies in its three major technological breakthroughs.

The project introduces a new high-precision, low-cost elevation measurement algorithm that maintains ± 0.5-millimeter accuracy even under strong construction vibrations.

It uses a vibration-noise suppression method that ensures accurate elevation measurement in complex, high-frequency vibration environments.

It features an independently developed intelligent paving measurement-control software that integrates BeiDou positioning with millimeter-level self-perception technology, advancing road paving from manual operation to intelligent, precision construction and improving its practicality in real-world projects.
