Claims31
A protective coating system for a bed of a railway structure having ballast and a railway track structure, comprising:
- a cure in place waterproof membrane configured to be disposed on a bed of the railway structure, wherein the waterproof membrane forms a substantially waterproof seal on the bed of the railway structure and wherein the waterproof membrane is adhered to the bed of the railway structure;
- a ballast protection coating adhered to the waterproof membrane, the ballast protection coating including a filler and a resin, wherein the ballast protection coating is compressible;
- and
- wherein the ballast protection coating protects the waterproof membrane from damage caused by operation of the railway track structure, and wherein one or both of the waterproof membrane and ballast protection coating have dielectric properties.
A protective coating system for a railway structure, comprising:
- a cure in place waterproof membrane disposed on the railway structure and wherein the waterproof membrane is adhered to 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 filler compound;
- and
- a sealing layer disposed on the ballast protection layer,
- wherein the ballast protection coating is interposed between the sealing layer and the waterproof membrane along an entire span of the sealing layer.
A method of coating a deck of a railway structure with a protective coating, the method comprising:
- applying a cure in place waterproof membrane on the deck of a railway structure, wherein the waterproof membrane is applied by spraying the waterproof membrane on the railway structure and is adhered to the deck of the railway structure;
- applying a ballast protection layer on the waterproof membrane, wherein the ballast protection coating is applied by distributing the ballast protection coating 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.
