A method to produce an expansion joint for adjacent roadway slabs having an expansion gap therebetween. A recess is cut or formed into the surface of each adjacent roadway slab to create a pair of recesses parallel to and adjacent the expansion gap. The recesses are cleaned to a sound, dust-free and rust-free surface. A temporary form is inserted in the expansion gap between the adjacent roadway slabs. A mortar mixture of a slightly resilient polymer and aggregate is installed in each recess to form a pair of parallel nosings adjacent the expansion gap. High-strength filler blocks are encapsulated within the mortar mixture to reduce the volume of the mortar mixture and to thereby reduce the cost of the nosings. A temporary backing is inserted in the expansion gap between the nosings. An initially liquid sealant is installed between the nosings and on top of the temporary backing which will cure to form a flexible seal.
