Ground treatment

In conventional road construction and maintenance, large quantities of materials are excavated and removed and large quantities of imported materials are added. This process is costly and it also depletes natural aggregate resources and hence conflicts with Eurovia’s sustainable development policy. In-situ treatment techniques using existing materials have therefore undergone substantial development. Initially, these techniques were confined to earthworks, in which they were employed to stabilise poor soils for use as fill, but they are now frequently proposed for use at a variety of levels in the construction of a wide range of road infrastructure projects.
