Colgrill R® takes off at 2 airports in Madagascar
Both airports favored the Colgrill R® technique
Colas Madagascar implemented the concession contract for 2 Madagascan airports (Nosy Be and Ivato Airport in Antananarivo) between May 2017 and June 2018.
Both airports favored the Colgrill R® technique, a glass grid which increases the life of the asphalt and limits its sensitivity to permanent vertical deformations, with a structure designed by Colas Campus for Science and Techniques, for optimized structural reinforcement.
220,000 m² in all – (150,000 m² for Ivato and 70,000 m² for Nosy Be) were laid down in record time.
This was also the first time that Colgrill R® was selected for a runway used by EE-class wide-body aircraft.
