Product catalog summary

Introduction
The Spectra® Pavement Optimisation System by Tensar® is designed to enhance the performance of flexible pavement structures using Tensar TriAx® geogrids. This system creates a mechanically stabilised aggregate layer that improves overall pavement performance, suitable for applications ranging from car parks to highways.

Key Benefits

Reduced Pavement Costs: Construction costs can be reduced by 20% through material savings and faster construction.
Increased Pavement Life: Traffic capacity can be increased up to six times compared to traditional pavements.
Lower Whole-Life Costs: Enhanced trafficking performance reduces maintenance needs, leading to cost savings over the pavement's life.
Reduced Carbon Footprint: By using fewer materials, the system lowers CO2 emissions associated with road construction.

Tensar® TriAx® Geogrids
Launched in 2007, these geogrids maximize aggregate confinement, creating stiffer layers that improve trafficking performance. They have been successfully used in various climates and ground conditions worldwide.

Performance and Testing
The system delays early failure of flexible pavements by controlling aggregate displacement, reducing rutting and cracking. It is effective across all ground conditions and is recognized by road authorities globally. Tensar has conducted extensive testing to validate the system's benefits, including trials at the UK Transport Research Laboratory and the US Corps of Engineers.

Applications

New Highways: Faster construction and reduced maintenance requirements lead to significant cost savings.
Highway Reconstruction: Minimizes the need for deep excavation, avoiding conflicts with existing infrastructure.
Car Parks: Enables thinner pavements, saving resources and costs.
Heavy Duty Applications: Supports high trafficking loads even on weaker ground.

Support and Services
Tensar offers comprehensive design and construction services, including project-specific support, training, and proprietary software for cost-effective design solutions. Engaging Tensar's team early in a project can lead to time and cost savings.

Conclusion
The Tensar® Spectra® Pavement Optimisation System provides a cost-effective, environmentally friendly solution for enhancing pavement performance, reducing construction and whole-life costs, and accelerating project delivery.

Pavement Optimisation with the Tensar® Spectra® System The Spectra System uses the proven capability of Tensar TriAx® geogrids to create a mechanically stabilised aggregate layer that contributes to, and improves, overall pavement performance. Suitable for any flexible pavement application, from car parks to highways, Tensar mechanically stabilised layers can increase support to surfacing layers and reduce the rate of structural degradation, increasing pavement life. They can also cut aggregate and asphalt costs, by reducing overall pavement thickness for faster, economical and environmentally-friendly...

Tensar® Spectra® System: Mechanical stabilisation of aggregate layers for enhanced performance An aggregate layer stabilised with Tensar TriAx geogrids performs as a composite, due to the interlocking mechanism and particle confinement that develops between the aggregate and the Tensar stabilisation geogrid. This Tensar mechanically stabilised layer provides more effective support to the entire pavement structure than aggregate alone.
