发明名称 Roadway marker and process of and application for producing the same
摘要 A raised marker is produced by inserting molten resin material, which has been premixed with a hardner or catalyst, into an open mold so that the resin conforms to the shape of the mold. The mold, prior to the time the resin cures or sets up, is inverted and placed on the pavement so that the resin, itself bonds to the pavement surface. The mold may be removed or remains as a permanent shell for the marker. A parting agent is used when the mold is to be removed. Color pigments and/or inserts in the form of glass beads or other reflective elements may be incorporated in the resin. Mechanism is shown for automatically filling and depositing the molds.
