GAPMAN Walking Profilometer for Road Roughness Measurement

GAPMAN is Englo’s portable walking profilometer designed for accurate and efficient road roughness and pavement profile measurement. The device measures key surface parameters such as the International Roughness Index (IRI), average angle of inclination, rut depth, and other profile characteristics used in pavement quality control and road condition assessment.

Compact, ultra-lightweight, and easy to operate, GAPMAN is ideal for field surveys, road inspections, construction quality control, and pavement maintenance projects.
