Patent ID: 7740413

Claim:
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.
