RA-400
The ultimate output of the RA-400, which is capable of correcting over 200 road defects in a single day by a single individual, has been deployed by contractors looking to maximize productivity while finding a cost-effective patching solution. The driver-operated joystick performs a four-step spray injection process typically in less than one minute per repair. Including one of the largest emulsion tanks available in the market, the RA-400 patching boom extends and retracts providing a wide patching range with minimal required maintenance.
