Santiago, Chile — EZ Street cold asphalt airport runway patch
Santiago International Airport, runway one receives over 320 incoming flights a day, making it one of the busiest runways in all of south America.
The runway was built of concrete. Deterioration at the joints is a principle concern of maintenance officials. To date, the only cost effective method has been to repair using conventional concrete and hot asphalt.
The runway is closed for approximately 45 days a year between the hours of 12:30 a.m. and 3:00 a.m., leaving the works very little time to perform major repairs and scheduled maintenance. Swings in temperatures in the winter and summer make such repairs difficult as construction teams are forced to use products with short “pot” lifes.
The introduction of EZ Street airport runway asphalt patch as a repair product for the impact zone enabled the crews of the Santiago International Airport to perform substantial cut outs at any temperature and in any condition. One such repair was completed on July 29th at approximately 1:00 a.m. Crews set out to structurally repair a ½ square meter of concrete pavement, in a joint, with EZ Street airport runway repair. The initial temporary repair was also done with EZ Street airport runway repair and has performed well. The permanent repair was to be saw cut, debris removed, and EZ Street cold asphalt compacted to level.
This entire repair, including preparation, was completed in approximately 20 min with four men. Upon completion the patch was immediately ready for incoming airplanes.
A second EZ Street emergency patch was scheduled for permanent asphalt repair that evening. Upon inspection, airport runway personnel made the determination that a permanent asphalt repair would not be necessary as the EZ Street cold asphalt material application and performance was adequate.
