Abstract: A portable device for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. Emulsion oils are held and dispensed from a separate emulsion oil tank. An emulsion pump provides emulsion oils to a spray wand. The emulsion oil tank includes an emulsion rejuvenator apparatus which works to prevent separation of the emulsion oils. A control circuit actuates the rejuvenator any time that the emulsion pump is turned on to supply emulsion oils to a spray wand to spray emulsions onto the road repair site.

Abstract: A portable device is shown for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. A heat transfer oil chamber is located below the hopper compartment and is heated by a primary heat source during normal working hours of the device. A pair of electrically powered electric heat riser tubes extend in a longitudinal direction in a horizontal plane in the hopper compartment above the bottom wall of the compartment for heating the asphalt materials in the hopper compartment during non-working hours.

Abstract: A portable device is shown for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. A pair of electric heaters are submerged in a heating chamber located below the hopper compartment for heating the asphalt mix. Tack oils are held and dispensed from a separate tack oil tank.

Abstract: A device is shown for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. A dry, radiant heat source is located in a heating chamber below the hopper compartment and heats the asphalt mix. Exhaust stacks in communication with the dry heat means have a damper system for retaining heat within the heating chamber, the damper system being electronically controlled in response to the temperature within the body of the device.

Abstract: A portable cart for transporting and dispensing heated pavement repair materials that is capable of being moved and operated by one person, the cart applying a heated asphaltic/polymeric binder material. The cart comprises a heating chamber having an enclosed interior and providing dry radiant heat and a containment chamber located within the enclosed interior of the heating chamber, the containment chamber narrowing towards an opening. Fuel gas is used to provide dry, radiant heat to the road repair materials to create a fluid material to apply to the surface to repair. The cart further comprises a hand-operated gating means, wherein the material within the containment chamber is gravity-dispensed in a controlled manner. The cart is ideal for repairing cracks and filling expansion channels in concrete and/or asphalt roadways and driveways.

Abstract: A portable apparatus is shown for transporting heated pavement repair materials. The apparatus has a heat chamber with an enclosed interior. A mixing chamber is contained within the enclosed interior of the heat chamber and has an inlet for receiving pavement repair materials and an outlet for discharging mixed and heated product. Either a dry radiant heat source or a liquid heat transfer source can be utilized to heat the mixing chamber. The apparatus is used to dispense a pavement repair material which is aggregate free, which does not require compaction and which is self-leveling.
