Is rubber recyclable?

Yes - it is used along with Asphalt for road paving in many states. Creates a much easier ride for automobiles. This does not mean it is recycleable. This example is re-using it (or downcycling it). As far as I know, rubber is not recycleable, in the sense that you can not take old rubber scraps and somehow treat them to bond together into a fresh sheet of rubber. Glass is recycleable because you can take pieces and rework them together. Using them in asphalt is not recycling, it's simply using them as filler in the concrete/asphalt. It's much better than sending rubber to landfill, but it's not recycling per se. Once it is used in asphalt it's more or less impossible to recover.

Why do you sometime find rubber strips between the section of a concrete bridge?

Rubber strips, often referred to as expansion joints, are placed between sections of a concrete bridge to accommodate movement caused by temperature changes, settling, and vibrations. These joints allow for the expansion and contraction of the concrete without causing stress or cracking in the structure. They also help prevent water and debris from entering the bridge's underlying components, which can lead to deterioration over time. Overall, they play a crucial role in maintaining the integrity and longevity of the bridge.
