Design Research on Steel Deck Asphalt Pavement of Bridge with High Lognitudinal Slope and Small Turning Radius

Abstract:

Steel deck pavement is a world wide problem especially on special steel bridge.Based on the analysis on the construction problem and special requirements of steel deck pavment on the bridges with high lognitudinal slope and small turning radius,the paper presents a new kind of steel deck pavement,called ERS steel deck pavement.It contains three layers,such as Epoxy bonding chips layer(EBCL) and resin asphalt mixture(RA05) and stone mastic asphalt(SMA).EBCL is used as waterproof,bonding and antiskid layer,RA05 is used as an integrated layer and the SMA10 is used as a surface functional layer.Indoor test results show that ERS steel deck pavement has excellent performance and good workablity.The new pavement structure is used on the steel bridge connecting Hangzhou Bay Bridge with sightseeing flat.It solved the difficult problem successfully.

Key words:steel deck pavement; lognitudinal slope; small turning radius; epoxy bonding chip layer(EBCL); resin asphalt mixture (RA05); stone mastic asphalt(SMA)
