I hate concrete, especially on highways.
Why? Its bumpy, and you can't see the lines on the road so well. Look at the pic on the last page and you'll see they put black paint right after the lane markings so you can see it. That looks horrible!
When you're going fast on concrete all you hear is bump, bump, bump whereas asphalt is a smooth, quiet ride. When roads start to wear down asphalt can easily be repaired whereas concrete is a more difficult, expensive job. When concrete is left in a bad condition it gets even worse as there are more cracks resulting in a even bumpier ride that can take a toll on your car.
I've even seen some concrete highways that have been repaired with asphalt. Their cracks and potholes are filled with asphalt which looks horrible.
Asphalt, if built right and properly maintained, is much better than concrete. It also works better in Canada as asphalt can expand and contact better than concrete during the many freeze/thaws this country experiences when the temperature hovers around the freezing mark.
