To build better roads and keep highway workers safe, Minnesota looks to autonomous technology

Autonomous technology aimed at making Minnesota’s roads better and safer is the focus of two new projects. The first uses robots to conduct pavement density testing for stronger, longer-lasting roads. A second project is developing self-driving trucks equipped with mounted attenuators to protect highway workers from danger in short-term work zones. The two projects were the subject of a CTS webinar held on May 8.

In Minnesota and throughout the US, many asphalt roads are nearing the end of their service lives. Replacing these roads is a major public investment, so transportation agencies must ensure they’re being built to the correct standards. One key standard is asphalt density—the most important predictor of pavement performance. View the full article: CTS.UMN.edu
