This is a kind of restoring the tracks of the bitumen road surface with the modified emulsified bitumen watery slurry mixed materials and its job practice. Spread single layer modified emulsified bitumen watery slurry mixed materials on the bitumen road surface of 10 - 20 mm depth, and spread double layer modified emulsified bitumen watery slurry mixed materials on the bitumen road surface of 20 - 40 mm depth. The job practice of single layer modified emulsified bitumen watery slurry mixed materials is: close down the traffic, process the original road surface, lay samples, spread, appearance control, joint slots, initial maintenance and quality inspection. Other building steps of the lower layer job practice of the double layer modified emulsified bitumen watery slurry mixed materials are the same as that of single layer, except that the allocated proportion of the single layer modified emulsified bitumen watery slurry mixed materials is different and without quality inspection. The upper layer building steps are: spread, initial maintenance and quality inspection. It has such advantages as high abrading-resistant performance, thin structure layer, long using life, high building speed, fast molding, short building period, fast traffic opening, long building season, low resource waste, no deleterious gas euduction and so on.
