The road and bridges building demands detailed preliminary investigation of site planned for it.
Moreover, both the road surfacing and bridges demand regular maintenance. GPR allows to discover underground communication lines, cavities and other items without any costly test check by drilling.
Both the speed of investigations and low financial costs are important advantages of GPR use.

As a result of that investigations you can have information about base course structure, overall thickness of structure road layers, integrity of its structure (or maybe some cavities inside), to find the zones of spreading of underground waters, and zones of ground slumping and thinning out. Also there is possible to carry out low embarkments surveys.
Within the urban area the road works often lead to traffic congestions and an interruption of city transport system.
Therefore, the rapid road works are very important. GPR allows to reduce considerably the time for road investigations and to locate the possible accident-related places.

Another application of GPR is a service test of takeoff and landing strips surfaces, city squares surfaces and other big-scale concrete structures.
