ABSTRACT:
An apparatus for dispensing, mixing and applying coating constituents to traffic surfaces has a wheeled transport carriage that supports a reservoir for coating constituents that are to be dispensed. A dispensing system regulates the dispensing of coating constituents from the reservoir onto traffic surface portions that extend centrally beneath the carriage. A power drive system moves the carriage across selected portions of traffic surfaces, rotates a set of mixing and applicator tools that extend in a radial array beneath the carriage, and rotates a set of blending blades within the reservoir to maintain coating constituent homogeneity, with these functions characteristically being carried out concurrently during the dispensing of coating constituents from the reservoir. The power drive system includes a carriage-mounted source of rotary energy such as an engine, and provides for coordinated operation of the power driven components at appropriate relative speeds of rotation to facilitate the application of coating constituents to traffic surfaces in a desired manner and with desired uniformity. Method aspects of the invention reside in the coordinated manner in which separate sets of power driven components are operated to enhance the character and uniformity of coatings that are applied to traffic surfaces.
