The Hong Kong International airport HKG is home to the world’s busiest cargo gateway airport. In 2015, HKG moved over 4.38 million metric tonnes of air cargo. It is also one of the world’s business passenger airports accommodating over 68 million passengers that same year.
Operations at the world’s busiest cargo airport run 24/7/365 without stopping. Maintenance crews need a crack and joint repair material that can be applied in a wide range of conditions and be ready for service in minutes. Roadware Flexible Cement II is a tough polyurethane crack repair material that can be applied at any ambient temperature. It bonds very well to distressed concrete and forms a tough semi-elastic polymer that will withstand heavy airline traffic in about 15 minutes. Crews at HKG airport have relied on Roadware Flexible Cement II to make repairs whenever and wherever needed for over 5 years.
Here is a crack repair project at the CVG Airport in Cincinnati, Ohio. The upper terminal deck developed cracks parallel to the construction joints. Roadware Flexible Cement II™ was used to repair the cracks in 2005. Here are some pictures of the project over the years.
Here is a photo of the CVG terminal deck as of June 2010.
Roadware Flexible Cement II™ was used the repair the crack on the right in 2005. The crack on the left was repaired with Roadware 10 Minute Concrete Mender™ for comparison.
Finished repairs in 2005. Roadware Flexible Cement II™ on the left. Roadware 10 Minute Concrete Mender™ on the right.
Repairs as they appeared in 2006 after one year on service. Both are holding well. The Roadware 10 Minute Concrete Mender™ on the right shows yellowing, but is still performing well. The Flexible Cement II™ is slightly lighter on color, but looks perfect.
Here is the same repair in June 2010. After 5 years on service, everything looks good.
This is a close-up shot of the Flexible Cement II™ after 5 years of service. The repair is still holding like the day it was installed. Roadware Flexible Cement II™ is a good choice for outdoor repairs in structural concrete. The semi-flexible properties strike a good balance between road toughness and just the right amount movement absorption.
