摘要： Detectable warning areas (DWAs) and methods of forming the same are provided. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold. A peg may be inserted into the mixture in the dome-shaped cavity of the die-cast mold. The mixture may be allowed catalyze and harden in the dome-shaped cavity of the die-cast mold, then a molded dome may be removed from the dome-shaped cavity of the die-cast mold. A portion of the molded dome such as the peg may be inserted into a hole in a prepared substrate. The dome may also be prepared by grinding an outer top surface with a drilling attachment. The dome may instead be formed with the use of an insert and a mat template.

摘要： Detectable warning areas (DWAs) and methods of forming the same. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold or a reusable mat template with a grommet. A peg may be inserted into the mixture. The mixture may be allowed catalyze and harden.
