Description
Technical field
The invention belongs to the road and bridge engineering field, particularly, the present invention relates to a kind of bituminous concrete bridge deck pavement structure and paving method thereof.
Background technology
The unique advantages such as steel case beam is large, lightweight with its span, easy construction are used widely.Mat formation with prevailing roadway and Bridge Surface Paving by Cement is compared, the paving steel bridge deck service condition is more harsh, therefore also has higher requirement: the layer of at first mating formation should have good pavement performance, high and low temperature stability and water stability and water proofing property etc.; The steel plate conductivity of heat is better in addition, is prone to distortion when constructing under the high temperature, produces shearing force, and requirement is mated formation, and layer has good flexibility and distortion chases after from ability, and is owing to the repeated deformation of steel plate, also higher with the adhesion stress requirement of steel plate to the layer of mating formation simultaneously.Paving steel bridge deck is a difficult problem of road and bridge worker research always, and domestic a lot of paving steel bridge decks disease in various degree all occurred, rut, passing, cracking etc. soon.At present domestic application is more mainly contains three kinds of schemes:
1), cast asphalt concrete mats formation, when pouring asphalt concrete is mated formation temperature up to 210～260 ℃, the easy temperature distortion of steel plate, can require the deformation compliance of pavement material very high, than being easier to occur the crack.Simultaneously, the pouring asphalt concrete that uses self drainage to mat formation can't be mated formation at the larger Steel Bridge Deck of the gradient.
2), epoxy asphalt concrete mats formation, such as application number: 200610069010.6, patent name: method for constructing epoxy resin pitch concrete steel bridge surface, this patent documentation relates to a kind of method for constructing epoxy resin pitch concrete steel bridge surface.Job practices of the present invention adopts following steps: spray one deck bituminous epoxy water-proof tack coat on the Steel Bridge Deck Corrosion Protection coating layer; Preparation bituminous epoxy binder; Preparation mixes mineral aggregate; Preparation bituminous epoxy blended stock, the lower floor's epoxy asphalt concrete of the mating formation layer of mating formation; Roll; Joint-cutting; Spray the bituminous epoxy tack coat; Repave and load onto layer epoxy asphalt concrete layer of mating formation; Maintenance.Yet the epoxy asphalt concrete requirement bridge floor of mating formation does not contain any impurity, dust and moisture, and needs about two months the time could open to traffic after construction is finished, and the implementation condition harshness often falls flat in the practical application.
3), common SMA bitumastic concrete pavement, such as application number: 200510018289, patent name: Bituonen-concrete-steel bridge floor and paving method thereof, this patent documentation relate to a kind of Bituonen-concrete-steel bridge floor structure and paving method thereof.Bridge floor is comprised of the Steel Bridge Deck through derusting by sandblasting, bridge floor bonding agent, epoxy mortar and modified emulsifying asphalt adhesion coating, particulate formula asphalt concrete layer and SMA bituminous mixture layer from bottom to top.Paving method is first to the Steel Bridge Deck derusting by sandblasting, spreads successively bridge floor bond layer, epoxy mortar and modified emulsifying asphalt adhesion coating, particulate formula asphalt concrete layer and SMA bituminous mixture layer on bridge floor from bottom to top again.Common SMA bitumastic concrete pavement has opposing rutting deformation ability, and cost is lower.Yet common SMA concrete can not obtain desirable solution with the interlayer problem of being combined of steel plate, and common modified bitumen viscosity is lower, causes the anti-shear concrete ability inadequate, the phenomenons such as passing occur easily.The SMA concrete needs vibroroller cmpacting simultaneously, very easily causes the phenomenon of degree of compaction deficiency in the situation of bridge floor resonance, thereby causes the generation of early disease.
