// Jiaozhou Bay Bridge

The PERMIT was used in the construction of the Jiaozhou (or Qingdao Haiwan) Bay Bridge in China’s Shandong province. In December 2012 the bridge was listed by the Guinness World Records as the world’s longest bridge over water at 41.58km (25.84miles).

The iconic T shaped structure uses 450,000 tons of steel and 2.3 million cubic meters of concrete in a salt water environment. The bridge is designed to withstand an earthquake of magnitude 8.0 as well as impact collisions from sea vessels

Amphora’s PERMIT Ion Migration Test was used to investigate methods for improving the resistance of the concrete to the penetration of chloride ions within the cover region.
