When large areas of sub-soil need treatment and stabilising in the most economical way possible, with all materials staying on site; an In-situ approach may be appropriate.
For sites where open space may be at a premium or where the stock piling and treating of the sub soil for use at a later time may not be possible, the In-situ method is invariably the most appropriate. Large areas of virgin ground can be economically and immediately stabilised quickly and efficiently.
Open areas to be treated, such as estate roads, vehicle parking areas, or site access can all be made stable and useable. Even ground that is water logged or contaminated will benefit from this process. Using a specialist piece of machinery like a Wirtgen WR240 high performance cold recycling soil and stabilisation vehicle, the ground to be stabilised is treated in one continuous movement. The Wirtgen WR240 rotovates the sub-soil with the SMR binder being is added, along with additional moisture (if required) as part of a single process, with the soil then immediately being layered back to the required depth and compacted all in one pass.
The soil then achieves the required stability and load bearing performance and may be bitumen sprayed to weather proof the entire mat, before the appropriate wearing courses are added.
Projects delivered in a timely way: By opting for the SMR In-situ methodology projects can be completed in a fraction of the time that would have been needed had traditional extract and replace methods had been used.
Financial Savings: By undertaking all the sub-base stabilisation using onsite material and adding SMR stabilisation material, massive financial savings are made, and these are significantly less than if traditional methods had been used to achieve the same result.
Significant reduction in vehicle movements: By eliminating the requirement to send existing material to landfill and replace it with new imported aggregate, vehicle movements can be avoided.
Zero material to landfill: Not only are transportation costs removed from any project, materials to landfill are reduced to zero as are landfill taxes and the cost of purchasing and transporting new materials to site.
