The unit shall be trailer-mounted and designed to repair potholes, cracks or broad distressed areas in paved surfaces. The unit shall be capable of blowing water, dust and debris from the pothole or surface to be repaired. The unit shall then operate by applying a spray of hot asphalt emulsion on the cleaned surface to provide a tack coat and then inject emulsion coated aggregate to form a high density patch. Finally, the unit shall apply dry aggregate over the repair area. The pothole patching machine shall receive aggregate from a dump truck with a tail gate modified by the machine supplier to gravity feed the hopper box of the unit. The hopper box shall be designed to hold the aggregate before it enters the air stream created by the blower. The hopper box shall allow aggregate up to 2-1/2'' in size to pass into the system without clogging. The machine must also be capable of delivering patching material gently into a confined area without damaging or touching nearby objects. The hopper box shall be equipped with a slide gate. Aggregate shall be fed to the aggregate hose by a venturi effect when the blower is on. The aggregate conduit system shall consist of an abrasion resistant pipe connected to a flexible non-kinking hose, a minimum of 16' in length. The flexible hose shall be fitted with a vent flow nozzle. This nozzle shall contain a spray slot for coating aggregate. The flexible hose and vent flow nozzle shall be supported by a swing hose carrier. This device shall allow the operator to repair an area within a 17' radius from the center of the vertical support arm and shall be adjustable for height. The swing support arm shall swing into a position parallel to the axis of the trailer where it can be locked in place for travel. The carrier shall be equipped with a reversible handle bar control to enable the operator to control the hose and nozzle assembly without having to bear their weight. The handle bar control shall include controls to regulate the emulsion flow, open and close the gate, and throttle the engine. The unit shall also be equipped with a 4' long wand connected to a hose mounted to a take-up reel, which is used to seal cracks using the emulsion material contained in the emulsion tank. The emulsion tank shall be an ASME certified pressure vessel with a minimum 250 gallon capacity. The tank shall be properly insulated and shall thermostatically regulate the emulsion temperature. The unit shall be capable of utilizing cationic and antionic emulsified asphalts, such as CRS2. The emulsion clean-out tank shall be minimum 10 gallon capacity and, in the open position, allow for diesel fuel to flow through the emulsion line to prevent clogging.
