The condition of our paved and dirt roads during spring thaw/freeze cycles
shows the powerful effects of water without plants being involved. I think
plants merely take advantage of existing opportunity.

I usually observe this with relatively new pavement laid down over
an area that had weeds growing but graded off. The "weed" will push the
pavement up, volcano like and continue growing. Some examples of
questionable authenticity:

I haven't personally seen that but I won't deny the possibility. The grass that tries to grow through joints in my decades old driveway pavement hasn't succeeded in opening them up. A contractor offered to pretty up the driveway until I told him I fix cars on it.
