Abstract
A method and gap sealing assembly for sealing adjacent roadway slabs at the gap. Gap sealing members bridging the gap are positioned in end-to-end array. A resistance heater is positioned adjacent elastomeric end surfaces of the members and a rubber-like heat activatable bonding agent is positioned between the end surfaces. When the heater is energized, the end surfaces are bonded to each other to form a seal in situ.
