This process involves a soil upgrading procedure that consists of the precise mixing of soil with a hydraulic binder in order to produce a suitable sub-base and a G1 soil fatigue strength rating. The latter may be achieved by means of many stabilisers (such as cement, lime, ashes, and other substances used to modify the soil structure).

IN-SITU STABILISATION

Its major quality consists in a considerable reduction in aggregate transport costs since the entire stabilisation process takes place inside a self-propelled spreading mixer.

In-situ soil stabilisation comprises these procedures:

• Development of applicable formulas and methods of soil stabilisation,
• Development of soil sub-base height and planning documentation,
• Mixing all the process compounds,
• Mixture homogenisation; initial pavement thickening,
• Smoothing and final thickening using paving machines and graders,
• Finishing works.

STABILISATION IN FIXED MIXING PLANTS (IN PLACE)

MThis method ensures the computer-controlled precise and uniform mixing of aggregate, hydraulic binder, and water. The mixing plant can produce up to 200 tons/hour. The process ensures exceptional mixing of all the compounds and a uniform stabilising mixture.

The stages of mixture manufacturing are:

• Installation of a production plant at the raw material storage yard,
• Mixing of all compounds in compliance with the KMA 200-developed formula,
• Loading on vehicles,
• Incorporation of mixture using paving machines or graders,
• Thickening using vibrating rollers,

Individual compounds are batched automatically using the applicable formula and pre-programmed process control. This method helps produce a predefined mixture for conditioned soil layers, stabilisation, concretes, and specifically designed layers for individual tasks.
