Zusammenfassung: | The invention provides a pavement method of a steel bridge deck made from epoxy asphalt, comprising the following steps: (1) applying abrasive blasting for rust removal and anti-corrosion treatment to the steel bridge deck, and measuring an atmospheric temperature, an atmospheric humidity and a temperature of a steel plate in the process of the rust removal and coating operations; (2) carrying out a construction of a waterproof layer, wherein the spraying quantity on the steel bridge deck interface is 0.66 +/- 0.03 kg/m2===m and the same on the asphalt mixture interface is 0.45 +/- 0.03 kg/m2===m under the construction condition with a temperature ranging from 15 to 30 DEG C; (3) carrying out a construction of a bridge deck pavement layer, wherein the proportion of aggregates of a cold aggregate bin is determined based on the radio of the aggregates determined by the target mix proportion; the heating temperature of aggregates is controlled to be in a range from 130 to 140 DEG C; a sieving test is carried out |
