A detectable warning system, for tactilely signaling the presence of a terrain transition to a pedestrian, using a plurality of detectable warning domes that are arranged in a grid within a warning dome tiles. The warning dome tiles comprises heat resistant detectable warning domes and connecting surface. A base layer sheet of thermoplastic is applied and adhered to the pavement surface prior to the application of the detectable warning tiles. A top layer of thermoplastic is applied and adhered to, and conformed to the warning domes. The detectable warning domes protrude from the pavement surface in an evenly spaced pattern that is detectable by the pedestrian using a cane or other guidance instrument.

What is claimed is: 1. A detectable warning method, for installation onto a pavement surface in an installation area adjacent to a hazardous transition, using a plurality of monolithic warning dome tiles made of heat resistant material and including a veneer having a top surface, lower surface, and a plurality of warning domes arranged in a grid on the top surface of each the plurality of monolithic warning dome tiles, and further using a continuous uninterrupted top layer and a base layer that are sheets of thermoplastic, comprising the steps of: bonding a base layer of thermoplastic to the pavement surface within the installation area by laying the base layer upon the pavement surface and applying heat directly to the base layer, the base layer being configured to provide leveling and bonding of each the plurality of monolithic warning dome tiles within the installation area; creating a tile layer within the installation area by laying the lower surface of the plurality of monolithic warning dome tiles upon the base layer to substantially fill the installation area; and bonding a top layer of continuous uninterrupted thermoplastic to the tile layer, within the installation area, by laying the top layer onto the upper surface of each plurality of monolithic warning dome tiles within the installation area to substantially cover the tile layer and applying heat to the top layer. 2. The detectable warning method as recited in claim 1, wherein the step of bonding the base layer is preceded by the step of heating the pavement surface within the installation area remove moisture in the pavement surface and ready the pavement surface for bonding with the base layer. 3. The detectable warning method as recited in claim 2, wherein the step of bonding a top layer of thermoplastic to the tile layer is preceded by the step of heating the upper surface of the tiles to ready the tiles for bonding with the top layer. 4. The detectable warning method as recited in claim 3, wherein the warning dome tiles are made of earthen materials, and wherein the steps as recited are preceded by the step of kiln firing the warning dome tiles to remove moisture therefrom. 5. A detectable warning method, for installation onto a pavement surface in an installation area adjacent to a hazardous transition, using warning dome tiles made of heat resistant material and including a veneer having a top surface, a lower surface having adhesive, and a plurality of warning domes arranged in a grid on the top surface, and further using a top layer is a continuous uninterrupted sheet of thermoplastic, comprising the steps of: creating a tile layer upon the installation area by laying the lower surface of the warning dome tiles upon the base layer to substantially fill the installation area and bonding the tile layer to the pavement surface with the adhesive; and bonding a top layer of continuous uninterrupted thermoplastic to the tile layer by laying the top layer onto the upper surface to substantially cover the tile layer and applying heat to the top layer. 6. The detectable warning method as recited in claim 5, wherein the step of bond a top layer of thermoplastic to the tile layer is preceded by the step of heating the upper surface of the tiles to ready the tiles for bonding with the top layer. 7. The detectable warning method as recited in claim 6, wherein the warning dome tiles are made of earthen materials.
