Stabilizing Highway Infrastructure in Monterrey, Mexico

PROJECT OVERVIEW
Location: Monterrey, Mexico
Application: Subgrade Stabilization & Moisture Control
Scope: 45,000 m²
RELATED PRODUCTS
Long Fiber Nonwoven Geotextile
1.THE CHALLENGE
The expansion project faced highly expansive clay subgrade. Monterrey’s extreme weather led to:
Pavement Rutting: Rapid deformation under heavy industrial loads.
Reflective Cracking: Moisture buildup at the base causing surface fatigue.
Maintenance Risks: Significantly reduced service life of the highway infrastructure.

2.SOLUTION
CHANGFENG’s integrated dual-action system was deployed to provide reinforcement and drainage in one step:
Reinforcement: The CHANGFENG Biaxial Geogrid locks the aggregate, creating a “stiffened slab” that increases load capacity.
Moisture Control: The Filament Non-woven Geotextile acts as a separator and filter, facilitating rapid lateral drainage.
3.KEY BENEFITS
Reduced Costs: Reinforcement allowed for a 25% reduction in required aggregate thickness.
Efficiency: One-step installation of the integrated material saved 30% on labor time.
Durability: High resistance to chemical weathering and UV exposure, engineered by CHANGFENG.
4.THE OUTCOME
Twelve months post-completion, the section remains stable with:
Zero Rutting: No surface deformation under heavy industrial traffic.
Superior Drainage: Effective moisture management even after seasonal floods.
Optimized Lifecycle: Estimated 40% reduction in long-term maintenance costs using CHANGFENG technology.

PRODUCTS USED
1.Biaxial Geogrid with high strength
Mechanical Interlock: Offers excellent confinement to stop base aggregates from moving laterally thanks to its sturdy rib structure and good connection efficiency.
strong Tensile Modulus: Designed to avoid surface deformation by absorbing and distributing strong dynamic stresses from large vehicles.
Environmental Resilience: Made with cutting-edge UV stabilizers to maintain structural integrity over time in challenging semi-arid environments.
2.Non-woven Filament Geotextile
Superior Filtration: While maintaining a constant high water flow, the needle-punched long-fiber polyester (PET) structure keeps subgrade particles apart from structural stones.
Hydrological Performance: During heavy rainfall, excellent in-plane transmissivity quickly drains surplus moisture, reducing subgrade softening.
High Puncture Strength: Made to resist abrasive pressures during strong compaction and installation damage.
