摘要： 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.

摘要： When mounted to a vehicle, a dispenser ejects optical elements so that they have a component of movement that is parallel with the surface of the pavement to which the optical elements are to be applied. Preferably, the component of movement in that direction is more significant than a component of movement directly toward the pavement surface. A fluid assist causes the optical elements to be ejected from the dispenser nozzle at a velocity to at least partially counteract, and preferably match, the forward velocity of movement of the vehicle to which the dispenser is attached. Thus, in accordance with one specific aspect of the present invention, optical elements can be laid down upon marking material that has been applied to a pavement surface at a substantially reduced relative velocity to the road surface. By more closely matching the optical element velocity in a direction opposite the vehicle movement to the velocity of the vehicle, the optical elements can be laid down without substantial roll along the pavement marking material. This can be accomplished regardless of the size or mass of the optical elements. The result is that the retroreflectivity of the pavement marking is thus not compromised or negatively affected in either direction (i.e. in the direction of vehicle travel or in the opposite direction).

摘要翻译： 当安装到车辆时，分配器喷射光学元件，使得它们具有与要施加光学元件的路面的表面平行的运动分量。 优选地，在该方向上的运动分量比直接朝向路面的运动分量更重要。 流体辅助使得光学元件以从至少部分抵消的速度从分配器喷嘴喷射，并且优选地匹配分配器附接到的车辆的前进速度。 因此，根据本发明的一个具体方面，可以将光学元件放置在已经以基本上相对于路面的相对速度施加到路面的标记材料上。 通过更紧密地将车辆运动方向上的光学元件速度与车辆的速度相匹配，光学元件可以沿着路面标记材料而没有实质的滚动而被放置。 无论光学元件的尺寸或质量如何，都可以实现这一点。 因此，路面标记的后向反射性因此在任一方向（即，在车辆行驶方向上或在相反方向上）不受损害或不利影响。

摘要： A pavement marker has an unpotted upper shell and a lower base plate that together define a housing. A number of ribs are disposed in the housing interior oriented substantially perpendicular to the inner wall of the base plate. The upper shell has inclined end faces, an upper face, and is made of a plastic material having moderate to high flexural modulus and a high impact strength. The lower base plate has a planar inner wall and an opposed planar, pavement-engaging outer wall, and is made of a material having a Young's modulus of at least approximately 300,000 PSI (20.7.times.10.sup.8 Pascal). The ribs are formed unitarily with the inner wall of either the upper shell or the base plate, and extend upwardly from the inner wall of the base plate to the inner wall of the shell. A retroreflective lens is positioned on at least one of the first and second opposed side faces of the marker. The pavement marker resists delamination from a roadway surface when secured to the road with a soft adhesive.

摘要： A fiber-reinforced raised pavement marker made of a composite material comprising an isotropic mixture of a polymeric material, reinforcing fibers and a filler material. The results of finite element analysis and composite technology have been combined to produce a pavement marker having high flexural strength and impact resistance without the need for an impact-resistant shell. Durable, high strength composite pavement markers are made by casting a homogenous mixture of chopped glass fibers and a filler material in a polymeric matrix. Placement of a retroreflective lens within the mold followed by pouring and curing the composite material results in a finished product upon release from the mold.
