Abstract
An method and apparatus for coating transportation components such as a bridge deck with a coating. The coating includes a sealant and rubber mixed with a resin and a foaming agent. The apparatus includes a hopper for the rubber, a impingement gun for the resin and a gun assembly that combined the rubber and resin together at a combined nozzle for spraying.
Claims27
A protective coating system for a railway bridge structure having ballast and a railway track structure comprising:
- a waterproof membrane disposed on the railway bridge structure, wherein the waterproof membrane forms a substantially waterproof seal on the railway bridge structure;
- a ballast protection coating adhered to the waterproof membrane, the ballast protection coating including a rubber compound and resin and a foaming agent that induces the resin to foam such that the resultant hardened resin inhibits water intrusion, wherein the ballast protection coating is formed from a plurality of layers, wherein the ballast protection coating is compressible;
- and
- wherein the thickness of the waterproof membrane is less than the thickness of the ballast protection coating.
- wherein the ballast protection coating is configured to protect the waterproof membrane from damage caused by operation of the railway track structure.
A protective coating system for a railway structure comprising:
- a waterproof membrane disposed on the railway structure;
- and
- a ballast mat further comprising,
- a ballast protection coating disposed on the waterproof membrane, wherein the ballast protection coating is composed of, at least in part, a rubber compound and a foaming agent;
- and
- a sealing layer disposed on the ballast protection layer.
A method of coating a bridge deck with a protective coating, the method comprising:
- applying a waterproof membrane on the bridge deck, wherein the waterproof membrane is applied by spraying the waterproof membrane on the bridge deck;
- applying a ballast protection layer on the waterproof membrane, wherein the ballast protection coating is applied by spraying the ballast protection coating and a foaming agent on top of the waterproof membrane;
- and
- applying a seal coat on the ballast protection coating;
- wherein the seal coat is applied by spraying the seal coat on the ballast protection coating.
A system for applying a ballast protection coating to a transportation component, the system comprising:
- a reservoir for holding particulate rubber;
- a vacuum system for vacuuming the particulate rubber;
- a system for supplying a resin;
- a spray nozzle that simultaneously receives the particulate rubber and the resin and sprays the particulate rubber and resin so as to mix the particulate rubber and resin.
