Bridge deck pavement structure for orthotropic steel bridge
The invention discloses a bridge deck pavement structure for an orthotropic steel bridge. The pavement structure comprises a mica-containing epoxy anti-corrosion layer, a solvent-free epoxy resin water-proof layer, a hot melt particle bonding layer, a high-elasticity modified asphalt pavement lower layer, a modified emulsified asphalt bonding layer and a high-elasticity modified asphalt pavement upper layer from bottom to top, wherein the total pavement thickness is 6-8 centimeters; the hot melt particles are high-polymer particles of which the softening point is greater than 150 DEG C; the high-elasticity modified asphalt is modified asphalt of which the elastic recovery is over 95 percent at 25 DEG C; the pavement lower layer is formed by paving a fine-particle asphalt mixture prepared by mixing the high-elasticity modified asphalt with a mineral mixture; the pavement upper layer is formed by paving a fine-particle or medium-particle asphalt mixture prepared by mixing the high-elasticity modified asphalt with the mineral mixture. By adopting the pavement structure, the water-proof layer and the asphalt pavement layer are combined integrally through the hot melt particle bonding layer, so that the shearing strength and durability of the pavement structure are ensured.
