Physical stabilisation is the process of improving the geotechnical properties of a material through the addition of hydraulic binders such as cement and lime.
The stabilisation process has been successfully used for a number of years and depending on the blend of additives, CBR values in excess of 30% can be achieved.
Some of the geotechnical improvements that can be achieved using the soil stabilisation process are listed below:
The stabilisation process is applied through specialist mixing plant, namely a tractor pulled Stehr, a Wirtgen or the Allu PMX Power Mixer. The nature of this specialist mixing plant enables large volumes of material to be processed and realistic throughputs of >1500m3/day can be achieved.
Listed below are some of the benefits to on site stabilisation:
