I have seen the paint here with the glow in the dark pigment, not sure who the makers are. I think that the lines could surely be done with it on pavement, but having the whole road glow would allow you to see objects further ahead of what the head lights would illuminate, and anything in the road would appear as a dark spot since it would be covering the pavement and suppressing the light. The road lines would also appear as dark strips because they would be covering the concrete.
