The asphalt gives, allowing the road to move. As the road cools, it shrinks, opening up the gap. But the asphalt gets beaten down by traffic keeping the joint full. Every so often, maintenance crews have to come out and either grind down the asphalt or put some more in, to keep the surface level. Asphalt roads develop gaps also.
