Naue UnpavedRoad – modified GH – calculator for temporary access and haul roads

Advanced design tool for the construction of unpaved roads, providing precise, efficient, and cost-effective solutions for temporary road infrastructure.

Streamlining temporary road design with the modified Giroud-Han method

The Naue UnpavedRoad – modified GH calculator allows engineers to develop optimised designs that enhance road stability and reduce construction costs.

Its design methodology, based on the proven Giroud & Han approach (2004), has been refined to incorporate the advanced performance properties of Naue Secugrid® geogrids and Combigrid® geocomposites. This ensures a more efficient, safer, and sustainable road construction process.

Streamlining pavement design with AASHTO guidelines The Naue PavedRoad – AASHTO calculator enables engineers to develop optimised designs that align with the strict requirements of AASHTO. By integrating performance data from Secugrid® geogrids and Combigrid® geocomposites, the tool provides accurate predictions of two key improvements: Reduced unbound layer thickness Extended service life of paved roads
