Abstract

A detectable pavement warning assembly includes a web having a plurality of projections attached to one another by linear connectors, a planar cover with a series of apertures for receiving the projections therethrough and an adhesive sheet. In use a rigid substrate such as a sidewalk is selected, and a primer is applied. The web, cover and adhesive sheet all pre-assembled are placed on the primed substrate. Next, the warning assembly is heated with an open flame to soften and fuse the pavement warning assembly with the primed substrate. The projections will remain extended sufficiently above the cover to provide a warning to pedestrians that walk thereon, such as when approaching a traffic area or other hazard.

Claims (18)

1. A method of affixing a pavement warning assembly having a web with projections and an apertured cover to a rigid substrate comprising the steps of:

a) placing the pavement warning assembly on the substrate with the projections extending upwardly through the apertured cover; and

b) heating the pavement warning assembly to fuse the pavement warning assembly to the substrate.

2. The method of claim 1 further comprising the step of coating the substrate with a primer.

3. The method of claim 1 further comprising the step of heating the primed substrate prior to applying the pavement warning assembly thereon.

4. The method of claim 1 wherein placing the pavement warning assembly against the primed substrate comprises the step of placing the pavement warning assembly on a primer coated concrete sidewalk.

5. The method of claim 1 further comprising the step of walking on the pavement warning assembly while detecting the projections.

6. A method of affixing a pavement warning assembly having a web with projections, an apertured cover and an adhesive sheet to a rigid substrate comprising the steps of:

a) priming the substrate;

b) placing the pavement warning assembly on the primed substrate with the web projections extending upwardly through the apertured cover and the adhesive sheet beneath the web to contact the primed substrate; and

c) heating the pavement warning assembly to fuse the pavement warning assembly to the substrate.

7. The method of claim 6 wherein priming the substrate comprises the step of coating the substrate with an epoxy primer.

8. The method of claim 6 further comprising the step of heating the primed substrate prior to placing the pavement warning assembly thereon.

9. The method of claim 6 wherein placing the pavement warning assembly on the primed substrate comprises the step of placing the pavement warning assembly on a primer coated concrete sidewalk.

10. The method of claim 6 further comprising the step of walking on the pavement warning assembly while detecting the projections.

11. The method of claim 6 wherein placing the pavement warning assembly comprises the step of placing a thermoplastic pavement warning assembly on the primed substrate.

12. The method of claim 6 wherein placing the pavement warning assembly comprises the step of placing a thermosetting pavement warning assembly on the primed substrate.

13. The method of claim 6 wherein heating the pavement warning assembly comprises the step of heating a pavement primed with a polyurea-epoxy.
