The Eighth Avenue Elevated Highway in Cincinnati, USA is the main entrance to the western region of the city, and the bridge has a history of 80 years.

In October 2009, the Ohio Department of Transportation carried out a major overhaul of this bridge. The new bridge deck, pedestrian walkways, and collision walls were all protected with Kentucky concrete sealant curing agent - increasing the surface hardness, wear resistance, impermeability, and repairing shrinkage cracks of the concrete. The construction area of the project was 250000 square meters.

This once again proves that Kentek can not only be used on indoor floors, but also capable of protecting concrete surfaces in harsh external environments (such as UV radiation, acid rain erosion, freeze-thaw damage, crack repair, etc.), with superior technical performance.

According to US regulations, active silicate products used on outdoor pavement and bridge deck concrete surfaces must simultaneously meet the following four performance indicators:

1. Freezing and thawing cycles (weathering resistance): More than 100 times, with no cracks or peeling on the surface of the concrete.

2. Impermeability: The absorption rate is less than 1% after 48 hours and less than 2% after 50 days.

3. Anti slip performance: The friction performance of the treated concrete surface cannot be reduced by more than 10%.

4. Crack repair performance: meeting the repair indicators for sealing micro cracks in concrete.
