Infrasense Maps Subsurface Conditions on Lowell’s Route 133

The project utilized the Kontur DXG1820 sensor, a 20-channel system capable of capturing continuous five-foot-wide swaths of data. This approach moves beyond traditional single-channel methods, offering a multidimensional view of the road’s foundation. Analysts focused on identifying the placement and alignment of dowel and tie bars, while simultaneously measuring pavement thickness to detect potential voids beneath the surface. These findings serve as the foundation for future rehabilitation strategies, allowing engineers to prioritize maintenance based on actual structural performance rather than surface-level observations. By pinpointing exactly where critical components are missing or misaligned, the data enables more targeted remediation along this historic corridor.
