Betoflex® proves its worth in Calgary
With more than 15 million passengers per year, Calgary is the third busiest Canadian airport in terms of passenger numbers, just behind Toronto and Vancouver.
To solve the problem of constant surface damage on the waiting areas of taxiways Charlie and Alpha, the Calgary airport authorities called in Standard General Inc. Calgary, a subsidiary of Colas Canada in Alberta. The objective was to improve the resistance of the surface to rutting, completing the work as fast as possible in order to minimize disruption to airport operations. Already used on a number of infrastructure projects, Betoflex® was quickly selected as the ideal solution.
Formulated by Colas’ Campus for Science and Techniques, the asphalt mix was then modified by the subsidiary’s laboratory in Acheson, to adapt it to local standards, especially the temperature ranges involved when using bitumen (from + 64°C to - 28°C).
