About this detail

This expansion joint assembly occurs where concrete paving interfaces with vertical conditions such as existing sidewalks, curbs, or other structures. A half-inch pre-molded expansion joint material separates the concrete paving from the vertical structure, with reinforcing rebar discontinued at the joint. A backer rod with a bond breaker is placed within the joint space beneath a urethane joint sealant. The top edge of the concrete paving features a typical one-eighth-inch radius tooled edge.
