Asphault seems more weather resistant than concrete - concrete cracks really easily.

Concrete. Back in the late 60s and 70s, the interstate system was being born. concrete was laid from coast to coast. today, some of the original concrete is still on the interstate system. yes, it was expensive back then and even more so, today. Asphalt does not tolerate the weather as well as concrete. salt is the main villain of asphalt. salt works well, when its needed, but spring rains works itself underneath the asphalt and combines with the salt to destroy asphalt. this is a "pot hole". concrete does not produce this effect, immediately. Its thumbs up for concrete, in the long run.

I see Concrete in the long haul. It is more expensive to purchase, requires more effort to set the foundation, place the reinforcement, to pour and cure, but it lasts and lasts and lasts, and the patches that may some day have to happen are done with a significant amount of success. Asphalt is significantly inexpensive, requires less foundation, but many potholes develop at the joints as a result of water freezing, melting, freezing, melting then they break apart. Often times they require resurfacing as early as 2 years. Asphalt also seems to never really cure, though you can drive on it relatively soon after its laid, excessive traffic compacts high traffic areas and when the new surface is laid, it is usually laid right on top and is only as good as the layer below it. I do believe that Asphalt is very cost effective and the best solution for brand new roads as in country settings where the traffic is not as heavy as major roadways and highways. The road in front of my house was dirt, but they paved it with asphalt last year, and I am sooo happy. It was done in a matter of days rather than a matter of months, and the traffic flow is slow so it won't need to be replaced for many years.
