The invention provides a method for treating vehicle bump at a bridge head of a highway, which comprises the following steps: providing a road surface layer, a bridge head transition slab and a roadbed, and grouting the roadbed; digging out the bridge head transition slab in the position where the bridge head transition slab breaks and the pavement severely deforms, replacing the bridge head transition slab, excavating out the pavement, excavating out 0.5-1m of the roadbed, refilling the roadbed, and strengthening the top and bottom of the refilled roadbed by adopting steel nets; and leveling the bridge head with a complete transition slab by using an asphalt surface course, and arranging a reverse longitudinal slope to ensure smooth drainage. The method provided by the invention is used for treating vehicle bump at the bridge head in three aspects of roadbed treatment, transition slab treatment and pavement treatment, the roadbed is effectively strengthened, transverse and longitudinal slopes are smooth, the roadbed and the pavement are smooth in drainage, settlement at a rear bridge head is effectively prevented and treated, and construction and quality control are facilitated.
