Heavy Duty Pavements

Application Overview

The long-term performance of paved roads, from rural routes to major highways, is fundamentally dependent on a stable and uniform foundation. Weak or variable subgrades cause reflective cracking and premature failure in asphalt layers. Tensar’s AASHTO compliant design and pavement optimization system enhances the base layer’s stiffness, allowing for a reduction in overall pavement thickness while extending service life, delivering significant cost savings and improved performance.

Ground Challenges in Paved Roads Construction

Reflective Cracking and Premature Failure
Movement in weak or unstable subgrades translates through the pavement layers, causing cracks in the asphalt surface.
Reduced Service Life
Without a stable foundation, even well-constructed asphalt layers succumb to fatigue and failure much earlier than designed.
High Cost of Over-Design
Compensating for poor subgrade quality by increasing pavement thickness leads to excessive use of materials and higher capital costs.
Variable Soil Conditions
Inconsistent subgrade support leads to uneven settlement and localized failures, creating rough riding surfaces and safety issues.

POME’s Solution

High-Stiffness MSL with Integrated Geogrid Reinforcement
POME integrates Tensar geogrids within the base or sub-base to create a high-stiffness mechanically stabilized layer (MSL).
Bridging Platform for Even Load Distribution
The MSL acts as a bridging platform that distributes traffic loads more evenly across the pavement structure.
Reduced Subgrade Stress for Long-Term Performance
Reduces stress on the subgrade, improving long-term pavement performance and durability.
Optimized Thickness, Material Use, and Lifecycle Cost
Enables optimization of the overall pavement thickness, material use, and lifecycle cost.
Validated Design Backed by Research and Testing
Tensar’s design approach is backed by extensive research and full-scale testing, compliant with AASHTO requirements and local authority criteria for design and performance validation.
