Most asphalt damage comes from water getting under it and freezing. That shouldn't be a problem in a tunnel. But I'd assume they would use a concrete surface

Most asphalt damage comes from water getting under it and freezing. That shouldn't be a problem in a tunnel. But I'd assume they would use a concrete surface in any case.
- mjhay 4y agoUnderground things are more susceptible to flooding, not less. That's why basements flood so much.
- jandrese 4y agoBut they are far less susceptible to freezing. It's not the water that kills the road, it is the ice. Well, water can erode away the material underneath the road, but if this is happening in your tunnel you have serious problems.

- jandrese 4y agoCalifornians just drive too much.
