摘要： A method for tooling a pattern of retroreflective microcubes, which pattern can be subdivided into smaller increments within which there are straight line tooling paths, none of which pass through an otherwise solid part of the incremental pattern. The tooling paths within the various increments need not be parallel to a common plane. Various adaptions of the method enable the tooling of a number of specific microcube shapes and for modifying such optical properties of the microcubes as entrance angularity, incidence angularity, orientation angularity, observation angularity, percent active aperture and retroreflectance. Specific techniques govern the pre-selection of cube parameters such as cube axis cant, cube apex decentration, and cube boundary proportions, which parameters can be adjusted independently of each other. Designs tooled by the method can have 100% active aperture at near zero degrees entrance angle. The method involves providing a plurality of plates of micro thickness, each plate having at least one end comprised of a material that can be tooled with polished surfaces by means of an appropriate tool, tooling on said end of each plate an increment of the pattern, and assembling the plates together in various ways to form a master. Retroreflective articles made by means of this technique are expected to provide superior performance when used in pavement markers, highway signs and other applications.

摘要： A roadway marker comprises shell molded of suitable plastic and having an internal honeycomb configuration. A base plate extends over the lower surface of the shell covering the honeycomb arrangement and defining a plurality of chambers internal to the shell. The plate is provided with a plurality of apertures, each opening to a chamber. When the marker is installed, adhesive material flows through the apertures and into the chambers. Before the adhesive sets, it forms mushroomed-shaped configurations over the top inside surface of the plate. The mushroomed configurations create a strong mechanical bond between the plate and the associated roadway surface. The large lower surface area of the plate also enhances bonding of the marker to the roadway.

摘要： A heated kettle for melting and mixing a thermoplastic resin into a homogeneous mixture has a helically-formed agitator which rotates about a central shaft in close proximity to the internal wall of the kettle. Fixed to the shaft at approximately the center of the kettle is a cluster of radially extending paddles. The paddles and agitator have opposite pitch when the agitator and paddles are rotated, the resin circulates along the wall of the kettle and thence through a central region of the kettle. The circulation action serves to thoroughly melt and mix the resin into a homogeneous liquid mass.

摘要： A pavement marker base is provided having a generally planar bottom support surface with an array of downwardly facing open chambers molded therein. Deformations are formed on the bottom surfaces of at least some of the walls dividing the chambers, and also preferably in the peripheral support surface of the marker base to provide additional downwardly facing surface area to mate with an adhesive material used to adhere the marker base to a roadway surface. These deformations may be characterized by a variety of surface shapes, such as arcs, rectangular notches, and dovetails. In the preferred embodiment, chamber walls include outwardly directed lips to engage the adhesive material. In another embodiment of the invention, a wire mesh covers at least some of the bottom surface of the marker base, and is imbedded within the bottom surface of the chamber walls and peripheral support surface. The mesh engages with the adhesive to provide a strong means of anchorage.

摘要： A method for producing a pelletized pavement marking mixture includes selecting an appropriate thermoplastic binder that is a solid at ambient temperatures and heating the appropriate thermoplastic binder in a reaction vessel to a temperature sufficient to form a liquid thermoplastic binder; forming a heated pavement marking mixture by adding a plasticizer and a filler to the liquid thermoplastic binder in the reaction vessel; forming a substantially homogeneous pavement marking mixture by blending the heated pavement marking mixture for period sufficient to substantially evenly distribute the plasticizer and the filler within the liquid thermoplastic resin while maintaining the heated pavement mixture at an elevated temperature; extruding the substantially homogeneous pavement marking mixture from the reaction vessel to form an extruded substantially homogeneous pavement marking mixture; and pelletizing the extruded substantially homogeneous pavement marking mixture. A pavement marking mixture consists of a substantially homogeneous mixture of pellets. Each of the pellets in the pavement marking mixture consists of a substantially homogeneous blend of a thermoplastic binder, a plasticizer, and a filler. The method for making a pelletized pavement marking mixture can be extended by adding a pigment and retroreflective particles to the heated pavement marking mixture.

摘要： Cellular retroreflective sheeting comprises a first film of thermoplastic material which has been formed to define arrays of minute cube-corner reflective elements on one face thereof. The reflective elements are covered with a second thin thermoplastic film and the two films together pass over a patterned roller where a series of sonic welding heads rapidly bond the films together forming small cells of retroreflective cube-corner elements in the pattern of the roller. Because the heat generated in the welding process is localized to the pattern of the roller, cell walls may be formed having narrow thickness yet good bonding of the films is achieved. Further, residual heat does not appreciably transfer to adjacent retroreflective elements, therefore, distortion of adjacent elements is minimized and a sheeting construction is achieved having superior brilliance and durability as well as maximum retroreflective capability over a wide angular range of incident light. Also disclosed is a method for forming such sheeting.

A pavement marking mixture consists of pellets, each of which consists of a substantially evenly blended blend of a thermoplastic binder, a plasticizer, and a filler. The pavement marking mixture is heated to melting and applied to the roadway surface.

摘要： A pavement marker comprising a base member and a signal device for sending a light signal to a driver of an oncoming vehicle further includes a longitudinally extending tire directing hood member that directs tire contact away from the upper edge, upper portion, and upper generally corner portions of the signal device front face, while allowing tire contact with the lower portion of the signal device front face. The signal device front face is at a predetermined recess depth in said pavement marker, and is at a predetermined angle with respect to the roadway surface. The marker can be either a snowplowable marker or a sun country marker. The signal device optionally can be mounted on a base member by a mechanical interlock. Optional drainage channels can be provided in the base member to allow drainage of fluid from in front of the lower portion of the signal device.
