Calgary International Airport (YYC), a major gateway for Western Canada, needed major maintenance and repair of its main runway and taxi areas. Wear and tear had left small ruts in the pavement, rendering aircraft unable to pull away from the jet bridges (walkways to aircraft) without a tow. Moreover, when the planes pulled out of the holding areas, they required extra thrust, spraying unspent fuel onto waiting aircraft behind.

           

Lafarge in Calgary has a long history of working with the Calgary airport authority and had previously trialed Duratough™ in several locations throughout the airport locality. The installation entails a two-stage process using a proprietary porous asphalt layer, which is then flooded with a highly cementitious grout to form a solid asphalt/concrete mass. The resulting surface offers very high resistance to point loading and sheer forces from the turning movements of aircraft.

 

Duratough offers substantial savings over alternative solutions because it doesn't require a long curing period. At YYC, the grouting was completed on a Saturday and aircraft traffic was permitted in the area the following morning, almost eliminating the downtime usually required for such repairs.
