Building a road involves a complex team effort, requiring engineers to determine optimal routes, navigate terrain, manage costs, and select materials for durability.

However, the future of road construction may shift towards automation.

In China, a 98-mile section of road has been built with minimal human intervention, using automated robots supervised by a small team.

This project, part of the Beijing-Hong Kong Expressway, was led by China Railway 11th Bureau and involved multiple state-owned companies and advanced machinery from Sany Group.

During construction, autonomous machines distributed materials, while drones monitored progress and ensured quality control.

The project achieved remarkable precision, completing the road in a single pass without needing corrections.

This “0 edge rolling” method minimized gaps and improved efficiency, raising questions about the potential for similar automated approaches in future road projects, XATAKAON has reported.

While the exact impact on workforce reduction and cost savings remains unclear, this initiative represents a significant engineering milestone in road construction.
