ABSTRACT:
A method of making a flexible, yet durable expansion joint that is at a general even grade with abutting roadway surfaces. The method includes cutting a recess into adjacent roadway slabs having a gap therebetween, and thereafter cleaning the recesses. A flexible membrane strip is placed across the gap from slab to slab and secured thereto. Then, the recesses and gap are substantially filled with a mixture of sealant and aggregate. A final layer of aggregate is applied on top of the mixture such that the final layer of aggregate is at about an even grade with the abutting roadway slabs.
