A road marker placement apparatus has a dispenser for dispensing a road marker, a carriage for carrying the road marker dispensed by the dispenser, and a drive arrangement for driving the carriage from a collecting position. At the collecting position, the carriage can collect the road marker from the dispenser. The carriage can place the road marker on the road while being driven by the drive arrangement.

The disclosure describes an article of manufacture and method of forming one or more paver or paver-like patterned preforms for application to a pavement surface. The pattern may be selected for functional or decorative purposes. These distinct thermoplastic pavement marking patterned preforms comprise at least four independent sections wherein each of the four independent sections are placed on a pavement surface such that the four independent sections are separate and distinct and the four sections have top surfaces that are coplanar and also different from one another wherein the difference is selected from the group consisting of: different shades, different colors, and different textures, and wherein at least two of the four independent sections that are contiguous with each other are different shades, colors, or textures and wherein no grout line exists separating any of the four independent sections that combined together comprise the patterned preforms.

A two-layer retroreflective article construction is enabled that produces higher wide-entrance-angle performance for signs and pavement markings. A single-layer overlay is enabled for existing signs and pavement markers that improve their entrance angle performance. Materials used in the construction of an article or an overlay are transparent to radiation in the range of 400 to 1000 nanometers and utilize TIR (total internal reflection). Minimum performance specifications are proposed that extend sign sheeting retroreflectivity specifications to entrance angles of 60 degrees. An innovative traffic sign design is enabled that increases the positioning performance of safety systems and automated navigation systems.

White pavement marking (100) being readily apparent to both the human driver and sensors on a vehicle in both the daytime and night time. The pavement marking comprises a nonporous binder layer (110) comprising a titanium dioxide-coated synthetic mica pearlescent pigment and retroreflective elements (120) distributed on at least a portion of the nonporous binder layer.
