Pothole Patcher

Pothole repairs made with hot mix that is not maintained at proper temperatures produces repairs that are short-lived and often require repeated applications. The TOTAL PATCHER TP4 combines all the tools for doing the job properly in one package.

The system has a self-cleaning, air-assisted tack coat system that uses the same wand to blow out the pothole with compresses air and apply the tack coat. Because the system is powered by air, the spray nozzle remains unclogged. There's no pump-driven tack coat system, and the emulsion is evenly sprayed into the pothole.

During the workday, hot mix is uniformly warmed and/or held to constant temperature by a hot oil heat-transfer system that includes a circulating pump and a thermostatically controlled propane burner. Stockpile mix can also be easily warmed for better handling. The insulated hopper prevents cold spots, helping to eliminate areas where the mix can harden. The insulated tack-coat storage tank is heated indirectly by radiant heat from the patching mix hopper. Also, leftover hot mix does not need to be wasted. Constant mix temperature can be maintained overnight or over the weekend with its thermostatically controlled electric heater. The electric heating system has a ground-fault interrupter system for personnel safety. Additional features include:

•Insulated, hydraulically powered steel doors
•Cleaning fluid system, including storage tank, pump, spray wand, and hose, is used to clean the mix hopper wall and hand tools
•Includes propane hand torch
•Operator controls located at rear curb-side
•Built-in deck
•Powered by the truck engine via a PTO and hydraulic pump
