Why Are the Roads So Hard?

They are not made of foam rubber because they would obviously be trashed the first day traffic traveled over them. Foam rubber is a very fragile material. They have tested various roadbed materials that would be more flexible, but they all breakdown too fast and cause the surface to cave in. They keep trying however. There are several stretches of Interstate highway here in central fl., that are constantly being used as test surfaces. There is one stretch of cement highway that has been there for about 40 years that has never had to be repaired. If cement was not so expensive and in short supply, I am pretty sure they would be made out of this cement formula. I do not think that the powers that control roads are so much concerned with our comfort as the longevity of the road surface.
