초록 ▼

A quantity of retroreflective granules includes glass members each having a refractive index of at least about 1.5. The quantity of retroreflective granules can be partially embedded into a binder material applied on the surface of a structure to provide a visual aid. A structure includes a retroreflective surface having an inclined face defined on at least a portion of the structure. The retroreflective surface also includes a binder material applied to at least a portion of the inclined face of the structure. The binder material has a thickness dimension of at least about 10 mil. The retroreflective surface further includes a plurality of retroreflective granules partially embedded in the binder material. The plurality of retroreflective granules have a density of at least about 0.06 pounds/square foot as embedded in the binder material. Each retroreflective granule includes a glass member having a refractive index of at least about 1.5.

1. A method of applying a retroreflective surface to an inclined surface on a structure, said method comprising the steps of: applying a binder material to at least a portion of the inclined surface, wherein a thickness dimension of the applied binder material is at least 10 mil; andembedding a plurality of retroreflective granules at least partially within the thickness dimension of the binder material, the plurality of retroreflective granules being coated with a hydrophobic coating and having a density of at least 0.06 pounds/square foot as embedded in said binder material, each retroreflective granule comprising a glass member having a refractive index of at least 1.5 and a diameter greater than about 0.012 in., wherein said retroreflective granules are discharged from a nozzle onto the inclined surface, the nozzle moving in a forward direction with respect to the structure, and the direction of discharge being in a backward direction relative to the movement of the nozzle with respect to the structure. 2. The method of claim 1, wherein the step of applying a binder material comprises applying a binder material having a thickness dimension of between about 10 mil and about 12 mil. 3. The method of claim 1 wherein the step of applying a binder material comprises applying a binder material in a generally horizontal direction along a length of the structure. 4. The method of claim 1 wherein said binder material is applied to said at least a portion of said inclined surface prior to assembly of said structure. 5. The method of claim 4 wherein said plurality of retroreflective granules are embedded in said binder material prior to assembly of said structure. 6. A method of applying a retroreflective surface to an inclined surface on a structure, said structure generally extending along a horizontal dimension, said method comprising the steps of: applying a binder material to at least a portion of the inclined surface, wherein a thickness dimension of the applied binder material is at least 10 mil; andembedding a plurality of retroreflective granules at least partially within the thickness dimension of the binder material, the plurality of retroreflective granules having a density of at least 0.06 pounds/square foot as embedded in said binder material, each retroreflective granule comprising a glass member having a refractive index of at least 1.5 and a diameter greater than about 0.012 in., wherein the said retroreflective granules are applied from a nozzle onto the inclined surface, the nozzle aimed in a discharge direction that is oriented at an acute angle with respect to the horizontal dimension of the inclined surface. 7. The method of claim 6, wherein the acute angle is between about 30 degrees and about 50 degrees with respect to the inclined surface. 8. The method of claim 6, wherein the acute angle is between about 40 degrees and about 50 degrees with respect to the inclined surface. 9. The method of claim 6, wherein the acute angle is about 45 degrees with respect to the inclined surface. 10. The method of claim 6, wherein the nozzle moves in a first direction relative to the structure during application of the retroreflective granules. 11. The method of claim 10, wherein the nozzle is oriented with a discharge direction that is aimed in a direction away from the direction of movement of the nozzle. 12. The method of claim 6, wherein the step of applying a binder material comprises applying a binder material having a thickness dimension of between about 10 mil and about 12 mil. 13. The method of claim 6 wherein the step of applying a binder material comprises applying a binder material in a generally horizontal direction along a length of the structure. 14. The method of claim 6 wherein said binder material is applied to said at least a portion of said inclined surface prior to assembly of said structure. 15. The method of claim 14 wherein said plurality of retroreflective granules are embedded in said binder material prior to assembly of said structure.
