Maccaferri collaborated with the DRR’s Highway Maintenance Division to design an appropriate solution. Comprehensive site data, including water levels, soil conditions, and elevation profiles, were collected to support the analysis and design process.

After assessment, Maccaferri proposed a complete reconstruction of the existing pavement structure, including removal of the old asphalt, base, and subbase layers, followed by the installation of two key reinforcement materials:
(1) High-tensile uniaxial geogrid (ParaLink) — installed directly on the subgrade to improve bearing capacity and prevent lateral spreading or separation of the road structure.
(2) Biaxial geogrid (MacGrid EG) — placed beneath the base layer to enhance structural stability by providing tensile strength and load distribution.

Given the soft subgrade conditions, ParaLink was chosen for its superior tensile strength to reinforce the foundation before embankment construction, increasing subgrade bearing capacity and preventing structural displacement. The MacGrid EG provided additional stability by distributing loads evenly, thereby improving overall road performance and durability.

After reinforcement, the subbase and base layers were compacted to meet the required CBR standards (CBR ≥ 25% and CBR ≥ 80% respectively), followed by the final construction of the asphalt surface.

The combination of ParaLink and MacGrid EG not only improved stability and load-bearing capacity but also significantly extended the service life of the pavement structure.
