By requiring fly ash to be a mandatory component of all concrete, we create a formula similar to the "Roman Roads" There are viaducts made of this simple recipe still carrying fresh, cold water to Rome from the Alps, every day. Our roads won't need continual repair. The Autoban of Germany, once constructed, has functioned wonderfully using this knowledge. Foundations for houses in the US rarely last 100 years. Our houses deteriorate because the cement crumbles. Sidewalks would be as strong as stone. Curbs could really be curbs. Under many small town streets, are street worthy bricks made after the "Civil War" (it wasn't very civil). We can reclaim them, as we invest in real infrastructure Americans could again gain respect and build things that last.
