Spectra Pavement Optimisation System

Tensar’s Spectra Pavement Optimisation System is a comprehensive approach to optimising pavement structure based upon the proven capability of Tensar TriAx geogrids to create a mechanically stabilised aggregate layer that helps improve overall pavement performance and reduces pavement management costs.

The Spectra Pavement Optimisation System is more than just the mechanically stabilised layer, however. It includes all the specialist advice, experience, design tools, support and service that Tensar offers; it is a complete solution for pavement designers and contractors.

Suitable for a range of applications, from rural roads and car parks to major highways and heavy-duty industrial pavements, the system can reduce asphalt thickness by 15-30% and aggregate by 25-50%, without a loss in pavement performance. Using fewer materials means fast, economical and environmentally-friendly construction.

Spectra Pavement Optimisation brings long-term benefits too: more support for surfacing layers reduces the rate of structural degradation, reducing maintenance and repair requirements and increasing pavement life by up to six times that of non-stabilised pavements.

Better pavement performance with lower construction and maintenance costs

The Spectra Pavement Optimisation System is suitable for any flexible pavement application, from rural roads and car parks to major highways and heavy-duty industrial pavements.

The benefits of Spectra Pavement Optimisation:

  • Reduced construction costs: Construction costs are up to 20% lower than conventional designs by reducing excavation and disposal and by using fewer materials and accelerating construction programmes.
  • Thinner pavement: Asphalt thickness can be reduced by 15-30% and aggregate thickness by 25-50%, without a loss in pavement performance.
  • Higher capacity: Traffic capacity can be increased by up to six times that of traditionally-built pavements.
  • Longer pavement life: Thanks to the increased stiffness of MSL, cracking of asphalt and rutting of the whole structure is reduced, increasing pavement life.
  • Reduced whole-life costs: Increased trafficking performance can reduce maintenance and repairs, making pavement management more effective and delivering whole-life cost savings.
  • Reduced carbon footprint: Using fewer materials can reduce project carbon footprint.
