Build a Stronger Foundation for Infrastructure Projects with 3D Soil Confinement

It’s no secret that America’s infrastructure is desperately in need of investment. The American Society of Civil Engineers (ASCE) gave the country’s infrastructure an overall grade of D-plus in its 2017 Infrastructure Report Card—dangerously close to an outright failing grade. The ASCE estimates that the U.S. will need to spend nearly $4.5 trillion by 2025 to fix the country’s roads, bridges, dams, and other infrastructure.

Our nation’s roads and bridges—commonly referred to as the “backbone” of the U.S. transportation system—received grades of D and C-plus, respectively. These transportation systems are deteriorating due to advancing age, increasing use, and inadequate funding. This degradation leads to a significant cost to users in terms of time, money, and safety.

There are over 4 million miles of road in the United States, and the cost to maintain these roadways can vary greatly by state. Several factors determine maintenance costs, including the type of pavement surface, its current condition, its geographical location, average precipitation, number of annual freeze/thaw cycles, and frequency of use.

Three-Dimensional Geocells Provide Solutions to Aging Infrastructure

The long-term performance of infrastructure construction projects depends on the strength of the underlying soil. Through an interconnected honeycomb-like network, 3D geocells confine and stabilize soils that would otherwise be unstable under loading. The GEOWEB® 3D Soil Stabilization System is the industry’s most complete geocell system, designed with fully engineered components to withstand the most challenging site conditions. These components are built for strength, durability, speed of installation, and long-term performance.

Extend Pavement Life with the GEOWEB® System

When incorporated into the base layer under asphalt or concrete, the GEOWEB® 3D Soil Stabilization System dramatically reduces the occurrence of rutting, potholes, and pavement degradation. The GEOWEB® system does this by performing as a semi-rigid mattress and distributing loads evenly over soft subbase soils, significantly reducing deflection and settlement.

Three-dimensional soil confinement delivers higher performance and offers adaptability with varying fill materials, subgrades, and loading stresses when compared to two-dimensional geosynthetic solutions. The positive effect on the pavement base layer results in up to a 30% reduction in required pavement thickness and an extended pavement life with lower maintenance requirements and costs.

 

Build Safer, Lower-Maintenance Road Shoulders

Road shoulders play a vital role in the performance of roads and highways. They provide additional structural support for the roadway and a safe area for drivers and emergency responders to maneuver in the event of an emergency. The GEOWEB® system creates stable shoulders that reduce typical maintenance by up to 3 times and protect sealed pavement from deterioration and edge breaks. The GEOWEB® road shoulders can be designed with permeable aggregate or engineered topsoil/aggregate infill to facilitate vegetation.

Stabilize the Surface Around Bridge Abutments

Using the GEOWEB® system, you can design and construct bridge embankments with topsoil/vegetation, aggregate, or hard-armor concrete infills. The flexible nature of the GEOWEB® panels allows it to easily contour to the slope face and around obstacles such as piles and abutments. The GEOWEB® system prevents erosion around the abutments, which reduces lifetime maintenance costs.

Whether it’s a new project or repair work, you can build stronger, lower-maintenance roads and roadway structures with the GEOWEB® system—and with your own road and highway crews.
