Was on the NJ parkway and was wondering, why it’s not smooth. The roads pavement kept alternating between a smooth asphalt to a rougher substance, probably concrete. Maybe I’m using the wrong term but I’m curious.

I’m in Florida, the freeways roads here change material (into concrete) when it’s elevated, so going over a road or water.
