Tensar Spectra Pavement Optimisation System

Product catalog summary

Introduction
The Tensar Spectra Pavement Optimisation System leverages the performance of a mechanically stabilised layer (MSL) using TriAx geogrids. This system aims to enhance pavement design by reducing construction costs and extending maintenance intervals.

Components and Design Tools
The system includes a Tensar MSL, which integrates granular layers with TriAx geogrids to form a composite structure. Design tools incorporate AASHTO 1993 methodology, life cycle cost analysis, and environmental assessments, allowing for performance-based specifications.

Benefits and Cost Savings
The Tensar Spectra System offers significant life cycle cost savings by extending pavement service life and reducing aggregate fill by up to 50% without compromising performance. It allows for increased traffic capacity without additional layer thickness, resulting in reduced initial construction, maintenance, and rehabilitation costs.

Research and Testing
Extensive research, including full-scale tests by the US Corps of Engineers and the University of Illinois, supports the system's efficacy. The research aligns with AASHTO's endorsement of geosynthetics in pavements, validating the stabilisation effects of Tensar geogrids.

Stabilisation Mechanism
Stabilisation is defined by EOTA as the improvement in serviceability of granular layers through particle confinement, achieved by the interlock mechanism of the geogrid structure.

Additional Resources
Tensar provides a range of literature covering geosynthetics in civil engineering, subgrade stabilisation, asphalt pavements, and more. Contact information for further inquiries and product specifications is available.
