Abstract: A method of waterproofing a bridge expansion joint, gap between a pair of bridge decks or a bridge deck and a ground deck, implemented through a layer of primer, an elastic membrane, a waterproofing membrane, a reinforced membrane, and a repaving process. As the first step, the layer of primer is applied to adjacent ends of the pair of bridge decks or the bridge deck and the ground deck. The elastic membrane is then shaped to an inverted dome and positioned within the gap as terminal ends of the elastic membrane are thermally bonded to the layer of primer. The waterproofing membrane is then thermally bonded to the layer of primer and the elastic membrane. Then, the reinforced membrane is thermally bonded onto the waterproofing membrane along the bridge expansion joint. The repaving process is then executed to install an asphaltic plug, completing the waterproofing of the bridge expansion joint.
