The Tensar Pavement Optimisation System is a comprehensive approach for optimising pavement performance using Tensar TriAx® geogrids. The system uses the multiple benefits of a mechanically stabilised layer (MSL), which consists of aggregate stabilised by TriAx geogrid, to form a stiffer and more robust pavement structure.
The Spectra System is more than just the MSL. It includes all the specialist advice, experience, design tools, support and service that Tensar delivers; it is a complete solution for pavement design engineers and contractors.
The Spectra Pavement Optimisation System can lead the way to lower pavement construction costs by optimising pavement components. Research indicates that the use of the system will reduce asphalt layer thicknesses typically by 15-30% and aggregate layer thicknesses by 25-50%.
In addition, life cycle cost analysis indicates that the Spectra Pavement Optimisation System can extend long term service life up to five times the duration of unstabilised pavements of an equivalent thickness. Savings are achieved through reduced maintenance and extended rehabilitation intervals.
