Geophysical surveys are integral part of engineering geophysical surveys for highways. Application of nondestructive methods of roadway control, seasonable territory surveys in designing and constructing of highways makes it possible to minimize the risk of operation problems.

Geotex Testing Equipment Ltd. has the unique experience of providing engineering geophysical surveys in road control analysis and in designing and construction of new routes. On conducting of surveys it is used domestic  manufacture technique which makes it possible to conduct works at a rate up to 80 kilometers per hour.

APPLICATIONS

Engineering geophysical surveys for highways and overbridges construction

Determining thickness of road pavement structural layers

Detection of subsidence

Detection of nonsolid and watered zones

Study of engineering geological conditions of the zones liable to deformation:

• determining occurrence level of subsoil water existence
• mapping of bedrock foundation roof
• locating zones of specific subsoil spread (peat, silt, salt subsoil etc.)
• permafrost top tracing
• detection of heavy icy rocks
• examination of taliks, supercooled water brines with permafrost
• examination of permafrost dynamics (seasonal freezing zones)

Mapping of underground utility lines

Study of dangerous engineering geological processes:

• landslides,
• floating earth,
• karstic phenomena

Checking highway pavement structure compliance with project documentation

THE FOLLOWING EQUIPMENT IS APPLIED:

• OKO-2 Ground Penetrating Radar
• LAKKOLIT X-M3 Multichannel Seismic Station
• ERA-MAX Electrical Exploration System
• ERP-1 Digital Electrical Exploration System
