KEZAD Foodhub Paved Road with Tensar H-Series
Tensar® HX5.5 Geogrid stabilisation in Action
Tensar International LLC (Tensar) was approached by the Consultant, AECOM to provide a more cost-effective and sustainable solution for flexible pavements within the KEZAD Foodhub Development Project. Tensar’s alternative design was implemented, incorporating a Tensar Mechanically Stabilised Layer (MSL) with reduced layer thicknesses compared to the conventional unbound construction.
The consultant was seeking a cost-effective and sustainable alternative that met all the client’s requirements, accelerated the construction time,and maintained the required pavement design life.
By incorporating Tensar geogrids, the required thickness of both the asphalt and base course layers was reduced, delivering an overall saving in pavement cost. A minimum geogrid overlap of 300 mm was specified to ensure individual rolls perform together as a unified stabilising system. Recycled crushed aggregates were used as the base course material, supporting both sustainability and performance objectives. Beyond cost savings, the optimised pavement design also reduced construction time and lowered carbon emissions,improving overall project efficiency and reducing environmental impact.
