I'll bet they can. They just don't want to put in the time to do it. For instance, an engineering prof here in Milwaukee developed a paving process using fly ash that rivaled Roman roads. BUT, Wisconsin engineers don't seem to want to have roads that last longer. There is profit associated with repaving the highways every 3-4 years.

Yes, too bad we don’t have real capitalism in our country. Crony (leftist) capitalism is the culture of business now. I remember 25 years ago when “well, you have to cut corners and cheat to stay competitive!” was the mantra. Now it’s the “natural order of things.”
And the new roads every three or four years issue is rampant here in Ohio as well. In the mob-controlled counties, the work is so shoddy that they “have to” work on the roads the whole time between paving.
Someone made a mistake in my county the last time they paved the highway. It’s holding up as if it will last for quite a few more years, and it’s already on its way to the third winter. Yeah, somebody goofed big time. Whoever it was is probably already at the bottom of Lake Erie wearing cement overshoes.
