ABSTRACT:
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.
