Bridge deck asphalt paving process

The invention belongs to the technical field of asphalt pavement, and particularly relates to a bridge deck asphalt pavement process which comprises the following steps: firstly, carrying out sand blasting treatment on a bridge deck, removing impurities from the bridge deck, recycling shots, and cleaning impurities on the bridge deck; brushing a waterproof bonding layer on the cleaned dry bridge floor by using a roller brush; after the waterproof bonding layer is cured, paving an asphalt mixture prepared in advance at the paving temperature of 150-170 DEG C and the paving thickness of 20-30 mm, and uniformly rolling when the temperature of the pavement is reduced to 120-150 DEG C; when the bridge deck steel plate deforms under the action of temperature change or traffic load, the relative displacement among the waterproof bonding layer, asphalt and the bridge deck steel plate can be absorbed, the defects such as cracks and bumps are well overcome, and the waterproof and anti-corrosion functions are achieved o
