Systems and methods for automating the application of friction-modifying coatings

摘要

A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. Both the binder and the filler are precisely and accurately metered onto the substrate, ensuring uniform coating thickness and performance. The method of this invention also enables the use of different binding systems and precise control over mixing ratios for multi-component binders.

主权项

1. An apparatus for applying binder, the apparatus comprising:
a cylindrical tube capable of being attached to a moving platform, the tube being closed at each end; at least one cavity defined inside the tube; at least one upper opening defined in an upper portion of the tube, the at least one upper opening being capable of receiving binder into the cavity; one or more substantially collinear slots defined in a lower portion of the tube, wherein the one or more slots extend substantially across the length of the tube and are adapted for dispensing binder from the at least one cavity onto the surface of a substrate; and at least one tube-reinforcing flange circumscribing at least a portion of the tube, and sized for preventing internal pressure from distorting the tube.
