The OKO-2 GPR Road Set uses special horn antennas (400-2500MHz) suspended above ground level and fixed to the vehicle by car suspension. The complex offers the users the single-channel and multi-channel solutions for high resolution survey up to 80 km per hour.
Geotech has a big experience of geophysical research on highway and collaborates with the leading Russian Road Companies.
Application
Engineering geophysical surveys for highways and overbridges construction
•Determining thickness of road pavement structural layers
•Detection of subsidence
•Detection of non solid and watered zones
