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.

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; andat least one tube-reinforcing flange circumscribing at least a portion of the tube, and sized for preventing internal pressure from distorting the tube. 2. The apparatus of claim 1 wherein the at least one flange extends to the one or more slots in the lower portion of the tube. 3. The apparatus of claim 1 wherein the one or more slots comprise one slot extending substantially across the length of the tube. 4. The apparatus of claim 1 wherein the one or more slots comprise one slot extending substantially across the length of the tube, and the apparatus further comprises at least one tube-reinforcing flange circumscribing at least a portion of the tube and extending to the slot, and is sized for preventing internal pressure from distorting the slot. 5. A system for the automated application of a friction-modifying coating to the surface of a substrate, the system comprising: a vehicle;at least one binder storage vessel positioned on the vehicle;at least one binder metering device positioned on the vehicle and coupled to the at least one binder storage vessel for metering the flow of binder;at least one binder applicator coupled to the at least one binder metering device, wherein the binder applicator comprises: a cylindrical tube closed at each end;at least one cavity defined inside the tube;at least one opening defined in an upper portion of the tube for receiving binder from the at least one binder metering device into the cavity; andone or more substantially collinear slots defined in a lower portion of the tube, wherein the one or more slots extend across the length of the tube and are adapted for dispensing binder from the at least one cavity onto the surface of a substrate;at least one filler hopper positioned on the vehicle; andat least one filler flow controller coupled to the at least one filler hopper for metering filler to be applied onto the binder. 6. The system according to claim 5 wherein the vehicle is at least one of a truck and a trailer. 7. The system of claim 5 wherein the at least one binder metering device comprises a pump coupled to the at least one binder storage vessel for metering the flow of binder. 8. The system of claim 5 wherein the at least one binder metering device comprises a positive displacement pump coupled to the at least one binder storage vessel for metering the flow of binder. 9. The system of claim 5 wherein the at least one binder metering device comprises a control valve coupled to the at least one binder storage vessel for metering the flow of binder. 10. The system of claim 5 wherein the binder comprises an epoxy. 11. The system of claim 5 wherein the binder comprises a thermoplastic binder. 12. The system of claim 5 wherein the binder comprises a polymer. 13. The system of claim 5 wherein the binder comprises polyacrylic rubber. 14. The system of claim 5 wherein the binder comprises a catalyst to enhance the properties of the friction-modifying coating. 15. The system of claim 5 wherein the filler ranges in size from about 10 microns to about 100,000 microns. 16. The system of claim 5 wherein the filler comprises bauxite. 17. The system of claim 5 wherein the filler comprises at least one of rock, mineral, metal, and polymeric materials. 18. The system of claim 5 wherein the filler is silica-based. 19. The system of claim 5 wherein the filler comprises reflective material. 20. The system of claim 5 further comprising at least one mixer coupled between the at least one binder metering device and the at least one binder applicator for mixing the binder. 21. The system of claim 5 further comprising at least one motorized mixer coupled between the at least one binder metering device and the at least one binder applicator. 22. The system of claim 5 further comprising at least one distributor coupled to the at least one filler flow controller. 23. The system of claim 5 further comprising at least one heater positioned proximate to the at least one binder storage vessel for heating binder. 24. The system of claim 5 further comprising at least one heater positioned on the vehicle for drying a substrate prior to application of binder to a substrate. 25. The system of claim 5 further comprising at least one heater positioned on the vehicle for curing binder after application of binder to a substrate. 26. The system according to claim 5 wherein the at least one binder storage vessel comprises at least one pressurized binder storage vessel. 27. 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 opening defined in an upper portion of the tube, the at least one upper opening being capable of receiving binder into the cavity; anda slot defined in a lower portion of the tube, wherein the slot extends substantially across the length of the tube and is adapted for dispensing binder from the at least one cavity onto the surface of a substrate. 28. The apparatus of claim 27, further comprising at least one tube-reinforcing flange circumscribing at least a portion of the tube and extending to the slot, the at least one flange being sized for preventing internal pressure from distorting the slot.
