When paved and unpaved roadway surfaces are built over weak subgrades, base deterioration can lead to degradation. This causes unwanted deflections, rutting, and cracking in the surface layer. Using the GEOWEB^® Soil Stabilization System reduces the vertical pressure on roadways and provides a high-stiffness foundation. This increases the load capacity of the subgrade allowing it to more effectively handle heavy and repeated vehicle leads.

In the base layer under hard pavements, confinement of aggregate significantly reduces movement and settlement, increasing the life of the pavement. Unpaved roadways also benefit from a more stable surface that performs as an on-site stormwater “detention” basin, promoting infiltration at the source and reducing runoff.

Learning Objectives:

• Understand the benefits of using the GEOWEB Soil Stabilization System to stabilize surfaces for unpaved roads using low-quality fill.
• Discover how 3D-confined base material reduces cross-section and provides a more stable base, especially over soft subgrade soils.
• Learn how the GEOWEB system reduces vertical pressure and subbase movement.
• Learn how to design pavement that will help meet on-site stormwater regulations and low environmental impact goals.
