American recycled plastic bridge is in good condition

On the Malika River in the southern part of New Jersey, USA, there is a 16.8-meter-long bridge built from recycled carbonated water bottles and plastic coffee cups. The bridge has been used for more than one year so far, but the technical indicators are normal. it is good. The bridge was built using a new type of plastic mixture invented by scientists at Rogers University in the United States.
At first, the university doctors Noske and Ranvry tested two common plastics, high-density polyethylene (HDPE) for milk bottles, and polystyrene for making coat hooks. They found that 65% would Polyethylene is mixed with 35% polystyrene, and the resulting mixture is not only highly rigid but also less likely to break. They believe that because of the addition of polystyrene filling the voids in the polyethylene like sea-surface structure, this material becomes very strong.
Although as early as 1998, Northlock and Ranfry invented this new plastic formula, they did not hang on the Malika River until after the Thanksgiving holiday in 2002. All use recycled plastic bridges. The bridge weighs only half as much as a wooden bridge or a reinforced concrete bridge. It takes only 11 days to build and costs 75,000 U.S. dollars. The same traditional wooden bridge usually costs 350,000 U.S. dollars.
For the question of how long the bridge can be used, Leven, director of the Federal Bridge Technology Office, said: “Since there is no short-term material experiment method that can predict the structural performance changes of these materials after 50 years, the most reliable prediction is currently available. The method of bridge performance can only be the monitoring of the various structural changes during the operation of the bridge."
Norsk and Ranvry also believe that without the long-term reliability test, it is not suitable to use this technology to build large bridges on the highway, but the performance of this mixture is indeed superior to their expectations. The engineers of the US Federal Highway Department said that this represents a breakthrough in the use of recycled plastics. Building bridges with recycled plastics will have great market potential.
