Permanent forward or sideways displacement of the surface that leaves ripples, bulges or a pushed-up lip, most often at intersections, bus stops and steep grades. It points to an unstable mix that is too rich or too fine, or to a surface layer poorly bonded to the one below because tack was missing or too light. Repairs usually mean milling out the shoved area and replacing it with a stiffer mix.
Shoving at the stop bar again, there's a two-inch hump where the trucks brake, mill it out and put the heavy-duty mix back.
