Case Detail
Subgrade Stabilization of Desert Expressway (Desert Subgrade Project with high tensile cellular confinement systems)
Project Background: A 12 km desert highway is founded on loose desert sand. Long‑term passage of heavy‑duty trucks tends to cause pavement rutting and differential deformation.
Selected Solution: High‑tensile HDPE cellular confinement systems adopted as the subgrade bed reinforcement layer.
Construction: Level the desert foundation → lay high‑strength geocells → fill with local desert crushed stone and compact in layers.
Performance Outcome: Under 50‑ton truck loading, pavement deformation is reduced by 75%. Local‑material utilization cuts aggregate consumption and lowers project cost.
