Pavement marker, pressure-sensitive adhesive laminate to attach a pavement marker to a road surface, suspended pavement marker, and a pavement marking process featuring a road surface with a temperature below 15 ° c

摘要

A pavement marker includes an object, such as a sheet or a raised pavement marker body, having an upper surface useful as a pavement marking indicium and a lower surface, and a bottom layer of polyorganosiloxane pressure-sensitive adhesive in intimate contact with the lower surface. A pressure-sensitive adhesive laminate system for attaching a pavement marker to a roadway surface includes a first layer of pressure-sensitive adhesive material,such as a polyorganosiloxane adhesive, a second layer of pressure-sensitive adhesive material, and a layer of deformable material interposed between the first and second pressure-sensitive adhesive layers, wherein the deformable material of the interposed layer is characterized by high cohesive (shear) strength. A method of marking a pavement having a temperature below 15 DEG C. includes providing a pavement marker of the invention and contacting the pavement with the pressure-sensitive adhesive and applying pressure to the top layer to bond the pavement marking material to the pavement.
