Ground Penetrating Radars (GPR) for Roads and Bridges Construction - Construction & Construction Materials
The roads and bridges construction and repair demand of careful investigation of road surfacing state, quality of used concrete and geological assessment of ground structure under roads to find any heterogeneity. GPRs can be applied here for: tunnels, road surface thickness measure, runways state assessment. The important advantage of GPRs using – quick road surface assessment.
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 road surface thickness, 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. 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.
