The invention provides a concrete road pavement crack quick repairing method which comprises a stepping mechanism, a pouring mechanism and a crushing mechanism, the crushing mechanism is installed onthe stepping mechanism, the pouring mechanism is arranged right behind the crushing mechanism, and the pouring mechanism is installed on the stepping mechanism; the problems that in the using processof a concrete road, pits are formed in the road surface due to damage caused by long-term rolling compaction of vehicles, and local transverse and longitudinal cracks, missing edges and falling corners occur to many road sections, so that the road surface driving comfort and safety are seriously affected, and the road surface needs to be repaired are solved; however, when the existing concrete highway pavement is repaired; generally, new concrete is manually stirred on site, then the new concrete is directly poured into a pit slot, and the pavement is leveled to finish repairing, so that the mode has the defects of long construction time, low bonding force to the original cement concrete, easiness in falling, high manual labor intensity, low efficiency and high construction cost.
