Problem

The Denver International Airport (DIA) is the sixth-busiest airport in the United States so some detrition on their runways is to be expected. DIA needed to replace sections of one of its most heavily used runways, 17L35R, as well as the connecting taxiways as it was showing signs of distressed pavement panels.

Solution

Propex GEOTEX® 701 was chosen to be used as a bond breaker between the cement treated subgrade (CTS) and the new pavement. GEOTEX® 701 is a polypropylene, staple fiber, needle-punched nonwoven geotextile that provides separation between dissimilar materials and meets FAA specifications.

Solution

Performance

This was the first project DIA completed using federal stimulus money. GEOTEX is made in the U.S., which made it easy for the contractor to comply with the Buy America clause in the stimulus package. The runway was closed for 90 days allowing for 130,000 square yards of GEOTEX® 701 to be installed. The result yielded a runway strong enough to accommodate the newest generation of jumbo jets.
