Abstract: A pavement marking composition, methods of applying, and pavement markings produced therefrom. The composition is a two-part coating composition having an amine component including one or more aspartic ester amines and optionally one or more amine-functional coreactants, an isocyanate component including one or more polyisocyanates, and material selected from the group of fillers, extenders, pigments, and combinations thereof.

Abstract: The invention relates to a method of applying a two-component composition and in particular a two-component pavement marking composition as well as an apparatus suitable for mixing, dispensing and spraying small volumes of a two-component composition.

Abstract: A method of making a pavement marker including the steps of forming an array of pavement elements in a predefined pattern interconnected by a carrier web. A frangible connection is formed between a plurality of the pavement elements and the carrier web. After the array of pavement elements is applied to the pavement surface using an adhesive, a portion of the carrier web surrounding the pavement elements is removed or allowed to substantially deteriorate and dissipate, leaving an array of discrete pavement elements.

Abstract: A method for making a magnetic pavement marker having an array of magnetic pavement elements arranged in a predefined pattern interconnected by a carrier web. After the array of magnetic pavement elements is applied to the pavement surface, the portion of the carrier web surrounding the magnetic pavement elements is removed or allowed to substantially deteriorate and dissipate, leaving an array of discrete, magnetic pavement elements.

Abstract: The present disclosure relates to improved raised pavement markers having a totally-internal-reflective lens. The disclosure also relates to methods of manufacturing the raised pavement marker. The raised pavement markers described below include a housing connected to a totally-internal-reflective lens. The totally-internal-reflective lens includes a retroreflective element having a smooth surface generally opposite a plurality of cube corner elements. A film is attached to the retroreflective element at the apexes of the cube corner elements to form spaces, i.e., an air gap, between the film and the cubes. The film and retroreflective element cooperate to form the totally-internal-reflective lens. Light entering the retroreflective element through the smooth surface is retroreflected at the cube/air interface. Methods of manufacturing include, for example, forming a shell with the retroreflective element and attaching the film to the apexes of the cube corner elements.

Abstract: A retroreflective sheeting utilizing a particular polymer as the bead bond layer is disclosed. The polymeric bead bond comprises urethane and urea linkages, and has a stage prior to thermosetting in which it may be softened by the application of heat and in which it has a relatively nontacky character. The retroreflective sheeting disclosed possesses the unique combination of high reflectance and superior exterior durability.
