Dump-truck mounted apparatus for repairing asphalt comprises a truck engine which drives first and second hydraulic pumps located on the truck chassis. One pump supplies pressurized hydraulic fluid to operate a lift cylinder which raises and lowers the dump truck box, to operate hydraulic tools and to drive a hydraulic motor which drives an emulsion pump for expelling liquid emulsion from an emulsion storage tank which are located on a cabinet detachably mounted on the dump truck box. The other pump supplies pressurized hydraulic fluid to operate a hydraulic motor on the cabinet which, in turn, drives an air compressor on the cabinet to charge a compressed air tank on the cabinet for supplying pneumatic tools. Reeled hoses are provided for supplying hydraulic fluid and compressed air to their respective tools and for supplying emulsion from the storage tank. Engine heat is supplied via a liquid coolant to heaters in the emulsion storage tank and emulsion pump to liquify the emulsion. A solvent tank is provided on the cabinet to feed solvent to flush the emulsion storage tank and emulsion lines. The dump box includes improved tool storage compartments.
