Roadware 10 Minute Concrete Mender is great repairing surface cracks in a bridge deck. The flow-and-go application along with the 10 minute cure time allow repair crews to get on and off the bridge quickly. Traffic can be returned to the bridge in just 10 minutes after application.  In the Philippines, crews often work at night when traffic is low and working conditions are cooler.

Crews work in teams. One person shoots the Concrete Mender from 600ml cartridges, one person applies filler sand, and one person trowels the repair smooth.

What are the reasons DOT’s Roadware?

1) “Safety for the driving public.” Roadware repairs are ready for traffic in 10 minutes. Lane closure time is dramatically reduced.

2) “Safety for my crew.” The interstate is a dangerous work environment, the quicker repairs are made, the less exposure to the hazards of working on a heavily traveled interstate.

3) “Saves a lot of money.” Quick cure times, easy mixing, straight forward application, and good long term performance makes Roadware 10 Minute Concrete Mender a good value. After a few days of training, the crew was able to repair a bridge in half a day. One district in Wisconsin saved about $1500 per bridge over conventional repair methods. No overnight lane closures are needed and crews are more productive with less equipment requirements.

Matching repairs to exterior concrete with a broom finish.

Use Roadware MatchCrete™ Clear, quartz sand, and portland cement to repair cracks in exterior concrete sidewalks and decks with a broom finish. MatchCrete™ Clear is a non-yellowing polyurethane bland that sets fast, bonds very well and can accommodate exterior conditions.

Using Roadware MatchCrete™ Clear to repair cracks on the historic Stone Arch Bridge.

This week the City of Minneapolis used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface on the Stone Arch Bridge in Minneapolis, Minnesota.   The Stone Arch Bridge is unique to the Mississippi River and features 23 arches, is 2100 feet long and 28 feet wide.

The bridge was built by railroad baron James J. Hill in 1883 and served as a working railroad bridge until 1965.  Today the bridge is mostly used by walkers and bicyclists.  The bridge also hosts many festivals and public events in the summer months.

In preparation for the summer festival season, City of Minneapolis crews used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface. MatchCrete™ Clear is combined with matching rock to repair cracks and restore a consistent walking surface.

The process begins with routing out the cracks with a dry diamond blade
to remove loose dirt and debris. Clean and dry matching stone is placed
into the crack up to surface level.

Matching stone is added up to the surface level

Next, two-part blended MatchCrete™ Clear is poured into the repair up to the surface. This fills in all the voids between the stones and seals the crack.  MatchCrete™ Clear is a semi-ridged material that will support all kinds of traffic from pedestrians to industrial fork lifts.

See video MatchCrete™ Clear application video below:

 

Repairs will have a, wet” look for a few months and will naturally dull over time. A clear coat sealing over the entire surface will off-set this effect.

In a few months, Repairs with MatchCrete™ Clear will dull and blend into the surrounding concrete.

Over time, repairs will become less shiny.

Update: June 24, 2012.

MatchCrete™ Clear repairs 18 days later.

 

I revisited the repairs on the bridge 18 days later. The surface has been sealed.  The repairs are performing as expected.

Roadware MatchCrete Clear is available is 50ml and 600ml cartridges and two gallon bulk kits.

Google has spent the last few years mapping and photographing roads all over the world. If you know where to look, you can see actual concrete repairs with Roadware 10 Minute Concrete Mender™

The Google Map photo below shows actual bridge deck repairs with Roadware 10 Minute Concrete Mender™ on Interstate 279 in Pittsburgh, PA.  See all the lighter colored spots? Each one is a hole or spall filled with Roadware 10 Minute Concrete Mender™. The repairs here are over three years old. Thank you Roadware distributor, Express Polymers, Inc., in the Pittsburgh area for sending this project in.
