OPTIGRAVE & Concrete for 5-ha platform at the port of toamasina
Colas Madagascar was mandated to create a 5-hectare platform at the port of Toamasina.
This major operation made it possible to optimize structures with Optigrave®, high-performance roller compacted concrete:
- Gantry crane tracks
- Truck lanes for specific transport
- The container storage area
The study of OPTIGRAVE®, used as a base layer, was carried out at the Antananarivo Central Laboratory and made it possible to optimize cement dosages while maintaining the required performance.
Its implementation was carried out with a motor grader without any special finish because it did not serve as a wearing course.
All in all, 10,100 m3 of OPTIGRAVE® and 9,400 m3 of concrete were deployed at this site.
