Infrasense Maps Route 133 Pavement with 3D-GPR Survey
Lowell, Massachusetts – September 25, 2026 -- Infrasense, Inc. has completed a 3D Ground Penetrating Radar investigation covering approximately 1.37 miles of Route 133 pavement in historic Lowell, mapping dowel bars, tie bars and subsurface voids across the full corridor width.
Survey spans both travel directions, shoulders and center turning lane
The engineering team scanned the westbound and eastbound lanes, both shoulders and the center turning lane along the Route 133 corridor to evaluate pavement conditions and structural components.
20-channel sensor captures continuous five-foot-wide subsurface swaths
Data collection was performed with a Kontur DXG1820 sensor, which uses 20 independent channels to gather three-dimensional subsurface information across a continuous five-foot-wide swath, in contrast to traditional single-channel GPR systems.
