Pavement investigations are like that undertaken for Geotechnical Investigations however are generally shallow given that pavements are normally founded relatively close to the surface.
A pavement investigation will often include surface exploration including a walkover survey to observe existing conditions and performance of existing pavements and subsurface exploration of a site using drilling or other excavation methods. Subsurface exploration usually involves soil sampling, sampling of existing pavement materials for potential re-use or stabilisation in-situ test and laboratory tests of the soil and pavement materials samples retrieved.
Upgrading of exiting pavements with an appropriate pavement investigation and subsequent innovative pavement design have saved Millions of dollars for large projects.
Site Geotechnical have undertaken thousands of pavement investigations across Victoria.
