Unpaved Roads

Application Overview

Unpaved roads, such as haul, access, and farm-to-market roads, rely entirely on their unbound aggregate layers for strength. Weak subgrades lead to rapid rutting, poor performance, and high maintenance under traffic loads. POME’s geogrid stabilization interlock with aggregate to create a stiffened, mechanically stabilized layer that protects the subgrade, distributes loads efficiently, and significantly extends the service life of unpaved surfaces, even with reduced aggregate thickness.

Ground Challenges in Unpaved Road Construction

Weak Subgrade Soils
Inadequate soil strength leads to rapid deformation and rutting under wheel loads, requiring constant regrading and maintenance.
High Maintenance Frequency
Without Tensar geogrid mechanical stabilization, unpaved roads deteriorate quickly, leading to ongoing operational disruptions and costs.
Material and Cost Inefficiency
Conventional designs require thick layers of high-quality aggregate to achieve minimal performance, driving up project expenses.

POME’s Solution

Stiff Composite MSL Through Aggregate Interlock
POME’s geogrids confine and interlock with the aggregate to form a stiff, composite mechanically stabilized layer (MSL).
Higher Structural Stiffness & Bearing Capacity
The MSL increases structural stiffness and enhances the road’s bearing capacity.
Wider Load Distribution on Weak Subgrades
Distributes traffic loads over a wider area, reducing stress on weak subgrades.
Reduced Deformation and Rutting Under Traffic
Minimizes vertical deformation and rutting under repeated traffic.
Durable, Low-Maintenance Road Performance
Delivers a more stable, longer-lasting unpaved road that requires less maintenance.
