SoilTech Powers - Stabilisation durable des chaussées

La solution de stabilisation innovante de MetaFLO a permis de réaliser des économies, des gains de productivité et des avantages environnementaux essentiels pour maintenir un projet routier de grande envergure dans les délais et le budget impartis.

Location

Hidrolândia, GO, Brazil

Challenge

Traditional subgrade regularization methods are resource-intensive, even when managing soils containing a mix of silt, clay, lateritic gravel, and quartz gravel. These methods often require large volumes of water, resulting in high operational costs and prolonged completion times. To address these challenges, a sustainable and efficient solution was needed to optimize resource allocation, enhance soil durability, and boost site productivity.

Solution

MetaFLO applied 0.037% of SoilTech biopolymer to a 500x12x0.2m3 track to demonstrate the technology’s potential for road stabilization. After being diluted directly in a water truck and applied to the track, SoilTech binds with the soil to form a hydrogel, and improves the soil’s mechanical properties after it cures. The treated soil exhibited increased mass density, better compaction, enhanced layer stabilization, and improved impermeability.

Avant et après

Outcome

✓ COST SAVINGS

On top of being environmentally friendly, SoilTech’s fast-acting soil stabilization reduced fuel consumption and polluting gas emissions by 25%, and saved the client 3 hours of labor—resulting in a total cost savings of 20% compared to traditional methods.

✓ WATER SAVINGS

Using SoilTech instead of traditional subgrade regularization methods saved a total of 80,000 liters of water throughout the project, reducing total water consumption by 33% and avoiding excessive water usage.

✓ ROAD QUALITY

24 hours after curing, particle cohesion in the soil was enhanced, compaction was improved, and impermeability was increased, leading to a more durable, safe and resilient road surface.
