Ribas do Rio Pardo – MS, Brazil

ملخص المشروع

In this forestry operation, Hexatrem trucks carrying up to 200 tons of eucalyptus logs travel daily on unpaved roads. The high traffic volume and heavy axle loads caused rutting, erosion, and loss of bearing capacity, compromising logistical efficiency and increasing maintenance demands.
The challenge was to enhance the structural capacity and long-term durability of the roadway without resorting to costly or environmentally aggressive stabilization methods.

النتيجة

حتى في التربة ذات الطابع الرملي الغالب، أدى استخدام كمية لا تتجاوز 0.02% من SoilTech إلى تكوين أساس مستقر وقوي ومتين، مما أدى إلى خفض تكاليف الصيانة المستقبلية بشكل كبير.

السياق والتحديات

• Ensure load-bearing capacity and track stability.
• Reduce erosion and settlement caused by heavy truck traffic.
• Implement a long-lasting solution with minimal maintenance requirements.

الحل المنفذ

MetaFLO applied SoilTech, an innovative, seaweed-derived biopolymer. The product is environmentally safe and works by agglomerating soil particles, significantly increasing base strength and cohesion—even in highly sandy soils.

APPLIED FORMULATION

• 0.02% SoilTech + 2% CP II Cement*
• Layer composed of 70% natural soil (90% sand) + 30% graded crushed stone (BGS)
• Initial natural CBR: 2.7%
• Density: 1.77 g/cm³

*Note: In this application, SoilTech was used in combination with cement, yielding above-average performance. The biopolymer, however, can also be applied on its own or with reduced BGS content.

EXECUTION

The work was carried out using conventional equipment, including a soil recycler, water truck, and compaction rollers. Use of a standard motor grader ensured speed, operational simplicity, and an excellent cost-benefit ratio.

نتائج

الأداء التقني

• Final CBR: 126.7% (up from 2.7%)
• الكثافة النهائية 2.26 g/cm³
• Durability:
Extended service life with minimal maintenance

الإنتاجية والكفاءة

• Rapid execution using standard equipment, with special emphasis on the Watanabe Soil Recycler.
• High-quality surface finish and optimized construction processes, reducing overall execution time.
• Material logistics aligned with schedule and budget requirements.

خاتمة

SoilTech stands out as a differentiated solution for soil stabilization. In addition to being organically derived and environmentally safe, it requires very low dosages and can be applied using conventional water trucks and grading equipment. The product delivers improved strength, increased CBR, enhanced waterproofing, and low maintenance needs—all with an excellent cost-benefit ratio.
