A waterproof expansion joint comprises a ballast protection plate with one or more centering tabs. Waterproof receptacles, or T-cups, are used to provide a waterproof layer under the ballast protection plate and around the centering tabs. Sealing tape and a spray-based waterproof membrane are installed with the T-cups. Once the ballast protection plate is placed over the deck joint with centering tabs extending downward into the T-cups, a bond breaker is applied. Finally, a second layer of waterproof membrane is applied to the top of all elements of the waterproof expansion joint.
