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.

1. A method for waterproofing a bridge expansion joint, the method comprises the steps of: (A) providing a bridge expansion joint, wherein the bridge expansion joint is a gap between a pair of bridge decks or a bridge deck and a ground deck;(B) applying a layer of primer onto adjacent ends from the pair of bridge decks;(C) adhering an elastic membrane onto a central section of the layer of primer, wherein the central section is positioned along the bridge expansion joint;(D) adhering a waterproofing membrane onto a first terminal section and a second terminal section of the layer of primer and the elastic membrane, wherein the first terminal section and the second terminal section are oppositely positioned of each other along the bridge expansion joint;(E) adhering a reinforced membrane onto the waterproofing membrane along the bridge expansion joint; and(F) executing a repaving process in order to install an asphaltic plug. 2. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: providing new construction of the adjacent ends during step (A);cleaning the adjacent ends during step (B); andapplying the layer of primer onto a concrete top surface of the adjacent ends. 3. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: providing old construction of the adjacent ends during step (A), wherein the adjacent ends are covered with a layer of old asphalt concrete;removing a blockout section from the layer of old asphalt concrete along the bridge expansion joint in order to expose a concrete top surface of the adjacent ends during step (B); andcleaning the adjacent ends; andapplying the layer of primer onto a concrete top surface of the adjacent ends. 4. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: aligning the elastic membrane along the central section during step (C), wherein the elastic membrane includes a pair of outer sections and an intermediate section;placing the intermediate section within the bridge expansion joint in order to form an inverted dome shape; andthermally bonding the pair of outer sections to the central section. 5. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: aligning the waterproofing membrane along the first terminal section, the elastic membrane, and the second terminal section during step (D); andthermally bonding the waterproofing membrane to the first terminal section, the elastic membrane, and the second terminal section. 6. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: aligning the reinforced membrane along the waterproofing membrane during step (E); andthermally bonding the reinforced membrane to the waterproofing membrane. 7. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: placing a slip sheet over the reinforced membrane during step (F);paving a layer of new asphalt concrete over the waterproofing membrane and the slip sheet;removing the slip sheet in order to extract a strip of paving material from the layer of new asphalt concrete, wherein the strip of paving material delineates an opening; andinstalling the asphaltic plug into the opening. 8. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1 comprises the steps of: providing at least one curb, wherein the at least one curb is positioned across the first terminal section, the central section, and the second terminal section;providing a curb line splash-guard, wherein the curb line splash-guard includes a road section and a curb section;aligning the curb line splash-guard along the at least one curb after step (E);thermally bonding the road section onto the reinforced membrane and the waterproofing membrane; andthermally bonding the curb section onto the at least one curb, wherein the curb section and the road section are angularly positioned with each other. 9. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1, wherein the elastic membrane includes a top non-stick mineral/polymer and silica sand layer, a first modified bitumen containing styrene-butadiene (SBS) copolymer layer, a reinforced non-woven continuous fiber polyester mat stabilized with fiberglass thread spun bond polyester layer, a second SBS copolymer layer, and a bottom torch off film. 10. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1, wherein the waterproofing membrane includes a top non-stick mineral/polymer and silica sand layer, a first modified bitumen containing atactic polypropylene (APP) layer, a reinforced non-woven continuous fiber polyester mat stabilized with fiberglass thread spun bond polyester layer, a second APP layer, and a bottom torch off film. 11. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1, wherein the reinforced membrane includes a top non-stick mineral/polymer and silica sand layer, a first modified bitumen containing atactic polypropylene (APP) layer, a reinforced non-woven continuous fiber polyester mat stabilized with fiberglass thread spun bond polyester layer, a reinforced mat, a second APP layer, and a bottom torch off film. 12. The method for waterproofing a bridge expansion joint, the method as claimed in claim 11, wherein the reinforced mat is made from stretched steel mash. 13. The method for waterproofing a bridge expansion joint, the method as claimed in claim 11, wherein the reinforced mat is made from heavy-duty fiberglass. 14. The method for waterproofing a bridge expansion joint, the method as claimed in claim 1, wherein the curb line splash-guard includes a top non-stick mineral/polymer and silica sand layer, a first modified bitumen containing styrene-butadiene (SBS) copolymer layer, a reinforced non-woven continuous fiber polyester mat stabilized with fiberglass thread spun bond polyester layer, a second SBS copolymer layer, and a bottom torch off film.
