| 20110070025 | METHOD AND APPARATUS FOR REPAIRING POTHOLES AND THE LIKE - A vehicle mounted patching system for patching potholes and the like and incorporating method and apparatus for removing and flushing asphalt emulsion from the feed lines of the patcher which completely recycles the cleaning agent used to flush the feed lines, as well as eliminating any external discharge of potentially toxic materials. A cleaning agent is used to flush the feed lines. The emulsion is collected in a recovery tank and combined with fresh emulsion delivered from a storage tank when the collected emulsion reaches a given concentration. Electrical controls for operating both motors from a single power source employ arrays of cam-operated switches and a diode array polarized to prevent feedback of power from the power source to assure precision positioning of the multi-position valves to perform a given operation. | 03-24-2011 |
| 20110070024 | METHOD AND APPARATUS FOR REPAIRING POTHOLES AND THE LIKE - A vehicle mounted patching system for patching potholes and the like and incorporating method and apparatus for feeding materials used in patching operations as well as removing and flushing asphalt emulsion from the feed lines of the patcher vehicle to completely recycle the cleaning agent used to flush the feed lines after a patching operation, as well as preventing any external discharge of potentially toxic materials. Dry particulate is used to coat a pothole patch to permit immediate use. Rubber particulate impregnated with a fibrous material is used to assure bonding with the emulsion. A hydraulically-driven feeder feeds particulate into a pressurized conduit through a one-way air lock. A hydraulic pump provides mechanical power to the feeder and an air blower which pressurizes the conduit carrying the particulate to a dispensing head. A spray assembly is provided to spray fibrous material entering the feeder. | 03-24-2011 |
| 20090064901 | ROADWAY PATCHING COMPOSITION - An asphalt based mixture, which is an oil and water emulsion, comprises 15-30% V water; 34 to 80% asphalt cement dispersed as asphalt cement droplets; and 20-66% V emulsifiers. Other materials are selectively added to the composition to improve characteristics including stability, viscosity, cohesion, adhesion and resistance to cracking. | 03-12-2009 |
