Pavement Optimisation

Pavement Optimisation helps ensure pavement design meets a project’s priorities in the most economical way, striking a balance between reducing pavement construction cost with increased trafficking capacity and whole life performance.

Tensar’s Spectra Pavement Optimisation System uses the proven capability of Tensar TriAx geogrids to create a mechanically stabilised aggregate layer that contributes to, and improves, overall pavement performance.

Improving pavement design and performance

The enhanced structural characteristics, deformation resistance and increased stiffness of the mechanically stabilised layer allows designers to obtain greater performance from the entire pavement structure, resulting in more economical construction, reduced risk, improved performance, reduced waste and longer life.Suitable for any flexible pavement application, from car parks to highways, Tensar mechanically stabilised layers optimise road pavement design by increasing support to surfacing layers and reducing the rate of structural degradation, increasing  pavement life.

Improving pavement design and performance

Suitable for any flexible pavement application, from car parks to highways, Tensar mechanically stabilised layers optimise pavement design by increasing support to surfacing layers and reducing the rate of structural degradation, increasing operational life.

Tensar Spectra Pavement Optimisation delivers pavement design that:

  • Reduces construction costs: Construction costs are typically reduced by up to 20% compared with traditional pavement design, by using fewer materials and accelerating programmes.
  • Increases pavement life: Traffic capacity can be increased by up to six times that of traditionally-built pavements of the same thickness.
  • Reduces whole-life costs: Increased trafficking performance can reduce maintenance and repairs, delivering whole-life cost savings.
  • Reduces a project’s carbon footprint: Construction materials have high embodied energy in terms of CO2 emissions. Reducing the amount of materials used, by optimising the road pavement design, reduces the carbon footprint.
