Steel box girder bridge deck pavement layer with high stability and high vibration resistance

2014 
The invention relates to a steel box girder bridge deck pavement layer with high stability and high vibration resistance. The steel box girder bridge deck pavement layer comprises a steel plate (1), wherein a waterproof bonding layer (2), a modified epoxy resin structure glue layer (3), a polyester filament and geotechnical cloth combined layer (4), a first high-viscosity modified asphalt tack coat (5), a first high-viscosity modified polyester fiber mixed stone mastic asphalt mixture layer (6), a second high-viscosity modified asphalt tack coat (7) and a second high-viscosity modified polyester fiber mixed stone mastic asphalt mixture layer (8) are arranged on the upper surface of the steel plate (1) from bottom to top. The steel box girder bridge deck pavement layer has the advantages of improving the bonding strength of an asphalt concrete pavement layer and a bridge deck slab, and improving the combining performance of the asphalt concrete pavement layer and the bridge deck slab due to high strength, good elasticity and high toughness of a geotechnical cloth; the geotechnical cloth has good traction action on the whole bridge deck slab, and finally, the purposes that the bridge deck pavement layer is prevented from shearing fracture, the asphalt pavement is prevented from translation, upheaval and other diseases in a travelling process, and the stability and vibration resistance of the bridge deck slab are effectively improved are achieved.
