Reinstatement of RoadCem Stabilised Soils
Introduction
RoadCem soil stabilisation is 100% recyclable and as such the stabilised material can be rotovated back to soil with no residual by-products having to be removed from site. For temporary works projects where the topsoil will likely be stripped and stored on site it will be the subgrade soil which is temporarily stabilised.
We recognise and understand the importance of both the topsoil and subgrade soil units in agricultural land use and we make every effort to ensure both the physical and nutrient characteristics of the soils are minimally impacted by the stabilisation process. This involves initial detailed site sampling and laboratory testing through to reinstatement techniques and verification testing.
PowerCem UK know that every site and every project is different and as such a bespoke reinstatement process will need to be developed and agreed in advance of any site operations.
The following generic process gives a step by step guide to how the process can be managed to achieve a satisfactory reinstatement:
Pre-Construction Sampling and Testing
Reinstatement works by their very definition rely on having a clear set of benchmarks to use during the reinstatement process. With this in mind before any works are commenced on site sampling of both the subgrade and topsoil units is required. These samples will be taken at multiple locations across the areas intended for stabilisation, as well as at number of locations outside the intended stabilisation zone. The samples will act not only as control to inform the reinstatement works but also be used for laboratory testing to ensure the viability of a RoadCem stabilisation process.
At the same time as the site sampling manual Dynamic Cone Penetrometer (DCP) testing will be carried at numerous locations to determine the density profile of the topsoil and subgrade soils down to approximately 1m depth. This information will again be used as a control to confirm the reinstated subgrade soils have been returned to at least the same densification as before the stabilisation process was carried out. These results will be given as CBR values and will also assist with the design of the stabilised layer.
Determination of the Agricultural Land Classification grades for the areas in question will be confirmed by consultation with the regional ALC maps from Natural England, as well as understanding the existing land usage: Arable, Grassland & Forage, Vegetables or Fruit.
