Bridge deck pavement method for orthotropic steel bridge
The invention discloses a bridge deck pavement method for an orthotropic steel bridge. The pavement method comprises the following steps: (1) performing sand-blasting and de-rusting treatment on a steel bridge panel, and coating a mica-containing epoxy anti-corrosion layer; (2) coating a solvent-free epoxy resin water-proof layer; (3) spreading a hot melt particle bonding layer which is partially sunken into the solvent-free epoxy resin water-proof layer, wherein the hot melt particles are high-polymer particles of which the softening point is greater than 150 DEG C; (4) paving a fine-particle asphalt mixture to form a high-elasticity modified asphalt pavement lower layer; (5) spreading a modified emulsified asphalt bonding layer; (6) paving a fine-particle or medium-particle asphalt mixture to form a high-elasticity modified asphalt pavement upper layer. By adopting the pavement method, the construction difficulty is lowered greatly, later maintenance is easy, the universality is high, a pavement lower structure is durable and long in service life, only the surface needs to be maintained in daily use, overall repeated maintenance is avoided, and the investment in a full life cycle is lowered.
