Abstract:
A method to produce an expansion joint for adjacent roadway slabs having an expansion gap therebetween, which method comprises:a. cutting or forming a recess into the surface of each said adjacent roadway slab to form a pair of recesses adjacent said expansion gap;b. cleaning the surfaces of said recesses;c. installing a form spanning said expansion gap;d. installing a leveling layer of a semi-self leveling mortar mixture of slightly resilient chemically curing polymer and aggregate into each recess;e. placing high-strength filler blocks on top of said leveling layer;f. installing said semi-self leveling mortar mixture of slightly resilient chemically curing polymer and aggregate into each recess to form a pair of nosings parallel to and adjacent said expansion gap;g. inserting a temporary backing between said nosings in said expansion gap; andh. installing an initially liquid sealant between said nosings to form a flexible seal in said expansion gap between said pair of nosings.
