The suspension bridge of Maanshan Changjiang River Bridge is a three-tower sus-pension bridge with span arrangement of (350 + 1 080 + 1 080 + 350)m .The bridge deck adopts the orthotropic steel deck .To provide useful technical directions for the construction technique and pa-rameters for the steel bridge deck pavement ,besides the regular quality control ,the surface treat-ment and the construction of the testing section containing the waterproof binding layers on the deck of the main bridge were carried out .The parameters ,such as the walking speed of the sand blasting machine ,the mixing proportion of the abrasives ,the spraying technique for each layer of the waterproof binding layers and the spraying amount were determined .The construction of the testing section of the asphalt concrete (GA10 + SMA10) was carried out on the deck of the ap-proach bridge ,from the test ,the standard mixing proportion of the GA10 and the SMA10 in the actual construction was verified ,the parameters for the construction techniques of pavement sprea-ding and compacting were determined .A series of inspections were conducted after the completion of the testing section ,so as to confirm that the quality of the pavement in the testing section could meet the design requirements .The inspection of the deck pavement construction of the real bridge demonstrated that the construction techniques for the steel deck pavement and the parameters de-termined by the testing section could effectively ensure the construction quality of the steel bridge deck pavement ,and the pavement could meet the design and technical code requirements .
