Over the past decade, the main terminal apron at Tucson International Airport (TUS) was beginning to require heavy maintenance. Cracking pavement was creating debris and the subsequent risk of foreign object damage for aircraft engines. Maintenance personnel at the Arizona airport were consequently spending a lot of time patching the approximately 50-year-old pavement.
“It had greatly exceeded its life expectancy,” informs Mike Smejkal, senior director of development services for the Tucson Airport Authority. “It needed to be replaced because it was past the point of maintenance.”
